  • Performance and Optimization Isn’t Evil

    - by Reed
    Donald Knuth is a fairly amazing guy.  I consider him one of the most influential contributors to computer science of all time.  Unfortunately, most of the time I hear his name, I cringe.  This is because it’s typically somebody quoting a small portion of one of his famous statements on optimization: “premature optimization is the root of all evil.” I mention that this is only a portion of the entire quote, and, as such, I feel that Knuth is being quoted out of context.  Optimization is important.  It is a critical part of every software development effort, and should never be ignored.  A developer who ignores optimization is not a professional.  Every developer should understand optimization – know what to optimize, when to optimize it, and how to think about code in a way that is intelligent and productive from day one. I want to start by discussing my own, personal motivation here.  I recently wrote about a performance issue I ran across, and was slammed by multiple comments and emails that effectively boiled down to: “You’re an idiot.  Premature optimization is the root of all evil.  This doesn’t matter.”  It didn’t matter that I discovered this while measuring in a profiler, and that it was a portion of my code base that can take “many hours to complete.”  Even so, multiple people instantly jump to “it’s premature – it doesn’t matter.” This is a common thread I see.  For example, StackOverflow has many pages of posts with answers that boil down to (mis)quoting Knuth.  In fact, just about any question relating to a performance related issue gets this quote thrown at it immediately – whether it deserves it or not.  That being said, I did receive some positive comments and emails as well.  Many people want to understand how to optimize their code, approaches to take, tools and techniques they can use, and any other advice they can discover. First, lets get back to Knuth – I mentioned before that Knuth is being quoted out of context.  Lets start by looking at the entire quote from his 1974 paper Structured Programming with go to Statements: “We should forget about small efficiencies, say about 97% of the time: premature optimization is the root of all evil. Yet we should not pass up our opportunities in that critical 3%. A good programmer will not be lulled into complacency by such reasoning, he will be wise to look carefully at the critical code; but only after that code has been identified.” Ironically, if you read Knuth’s original paper, this statement was made in the middle of a discussion of how Knuth himself had changed how he approaches optimization.  It was never a statement saying “don’t optimize”, but rather, “optimizing intelligently provides huge advantages.”  His approach had three benefits: “a) it doesn’t take long” … “b) the payoff is real”, c) you can “be less efficient in the other parts of my programs, which therefore are more readable and more easily written and debugged.” Looking at Knuth’s premise here, and reading that section of his paper, really leads to a few observations: Optimization is important  “he will be wise to look carefully at the critical code” Normally, 3% of your code – three lines out of every 100 you write, are “critical code” and will require some optimization: “we should not pass up our opportunities in that critical 3%” Optimization, if done well, should not be time consuming: “it doesn’t take long” Optimization, if done correctly, provides real benefits: “the payoff is real” None of this is new information.  People who care about optimization have been discussing this for years – for example, Rico Mariani’s Designing For Performance (a fantastic article) discusses many of the same issues very intelligently. That being said, many developers seem unable or unwilling to consider optimization.  Many others don’t seem to know where to start.  As such, I’m going to spend some time writing about optimization – what is it, how should we think about it, and what can we do to improve our own code.

  • Benchmark for website speed optimization

    - by gowri
    I working on website speed optimization. I mostly used 3 tools for analyzing speed of optimization. Speed analyzing Tools: Google pagespeed tool Yslow Firefox extenstion Web Page Performance Test I am measuring performance using above tool and benchmark result as below like before and after. Before optimization : Google PageSpeed Insights score : 53/100 Web Page Performance Test : 55/100 (First View : 10.710s, Repeat view : 6.387s ) Yahoo Overall performance score : 68 Stage 1 After optimization : Google PageSpeed Insights score : 88/100 Web Page Performance Test : 88/100 (First View : 6.733s, Repeat view : 1.908s ) Yahoo Overall performance score : 80 My question is ? Am i doing correct way ? What is the best way of benchmark for speed optimization ? Is there any standard ? Is there any much better tool for analyzing speed ?

  • Is traditional JavaScript image pre-loading taboo

    - by Evan Plaice
    I remember the good-old-days (not really) back when I was still sucking the teet of Dreamweaver to build websites and the lure of playing copypasta with fancy built-in scripts (ex, image-swap) was like black magic. I'm pretty far removed from that now days but I was adapting a small site from it's original FrontPage (::cringe::) format to a standard HTML/CSS implementation and couldn't help wondering... should I should re-implement the JavaScript image pre-loading into the current version? Or, is there a better way? I don't want to block the page from loading by requiring the user to request all the assets withing the page by using the traditional JavaScript pre-loader method. I value giving the user something to look at ASAP, and there's some potential harm to my Google mojo by doing so. Is there a cleaner solution to prevent unnecessary page-reflows during loading? Such as, setting the static width/height dimensions through a CSS style attribute on the image element.

  • Git pre-commit hook: getting list of changed files

    - by Mikko Ohtamaa
    I am developing validation and linting utility to be integrated with various commit hooks, including Git one https://github.com/miohtama/vvv Currently validators and linters are run against the whole project codebase on every commit. However, it would be much more optimal to run them against changed files only. For this, I would need to know changed files list in my Git precommit hook (in Python) https://github.com/miohtama/vvv/blob/master/vvv/hooks/git.py What options I have to extract the changed files list (in Python if that matters)?

  • GPU optimization question: pre-computed or procedural?

    - by Jay
    Good morning, I'm learning shader program and need some general direction. I want to add noise to my laser beam (like this). Which is the best way to handle it? I could pre-compute an image and pass it to the shader. I could then use the image to change the opacity and easily animate the smoke by changing the offset of the texture lookup. I could also generate noise in the shader and do the same thing the texture was used for. Is it generally better to avoid I/O to the graphics card or the opposite? Thanks!

  • Pre baked fractures and explosion : I need an answer for C++

    - by Ken
    What are the prebaked or precomputed explosions or fractures from a programmer viewpoint ? I would like to know how to achieve this in C++ and how this things are usually considered (they are animations? textures?), it would be perfect if there will be some examples available or someone that can picture a broad view about this. I need to add a really small support for this in my code and i need an hint about how to start, i would like to do this on my own without other libraries.

  • Can compiler optimization introduce bugs ?

    - by ereOn
    Hi, Today I had a discussion with a friend of mine and we debated for a couple of hours about "compiler optimization". I defended the point that sometimes, a compiler optimization might introduce bugs or at least, undesired behavior. My friend totally disagreed, saying that "compiler are built by smart people and do smart things" and thus, can never go wrong. He didn't convinced my at all, but I have to admit I lack of real-life examples to strengthen my point. Who is right here ? If I am, do you have any real-life example where a compiler optimization produced a bug in the resulting software ? If I'm mistaking, should I stop programming and learn fishing instead ? Thank you !

  • Best open source Mixed Integer Optimization Solver

    - by Mark
    I am using CPLEX for solving huge optimization models (more than 100k variables) now I'd like to see if I can find an open source alternative, I solve mixed integer problems (MILP) and CPLEX works great but it is very expensive if we want to scale so I really need to find an alternative or start writing our own ad-hoc optimization library (which will be painful) Any suggestion/insight would be much appreciated

  • The Expert Secret to Search Engine Optimization - Effective Website Optimization

    Throwing keywords into a program that shows you how popular they are and then using those keywords without doing a little bit of preliminary research and answering some very important questions can just spell disaster. There are three questions that are extremely important to ask yourself before just doing random search engine optimization. And believe it or not those three questions are not, "What are the most popular keywords for my particular website?" Those questions are much more fundamental and strategic and they can be much more important to your overall efforts in getting your site ranked on the search engines.

  • Search Engine Optimization - How Search Engine Optimization Works

    There are many ways to direct extra traffic to your web site, but search engine optimization may be the best. Unlike many traditional types of advertising, such as banner ads, this technique does not cast a wide net and hope for the best. Instead, it takes the opposite approach, simply making your site easier to find for people who are looking for a site that is similar to it. This is a much more reliable method of gaining additional viewers for your site, especially because it only targets people who are interested in you in the first place.

  • What is the best retort to "premature optimization is the root of all evil"

    - by waffles
    Often I hear the sentiment ... "Why worry about performance, write slow code, get your product to market ... don't worry about performance. You can sort that out later" The culmination of this sentiment is: "... premature optimization is the root of all evil ... #winning" I was wondering, does anybody have a good retort to this one liner. Ideally an equally strong one liner that encompasses the reverse of this sentiment?

  • Web page database query optimization

    - by morpheous
    I am putting together a web page which is quite 'expensive' in terms of database hits. I don't want to start optimizing at this stage - though with me trying to hit a deadline, I may end up not optimizing at all. Currently the page requires 18 (that's right eighteen) hits to the db. I am already using joins, and some of the queries are UNIONed to minimize the trips to the db. My local dev machine can handle this (page is not slow) however, I feel if I release this into the wild, the number of queries will quickly overwhelm my database (MySQL). I could always use memcache or something similar, but I would much rather continue with my other dev work that needs to be completed before the deadline - at least retrieving the page works - its simply a matter of optimization now (if required). My question therefore is - is 18 db queries for a single page retrieval completely outrageous - (i.e. I should put everything on hold and optimize the hell of the retrieval logic), or shall I continue as normal, meet the deadline and release on schedule and see what happens? [Edit] Just to clarify, I have already done the 'obvious' things like using (single and composite) indexes for fields used in the queries. What I haven't yet done is to run a query analyzer to see if my indexes etc are optimal.

  • Why would this Lua optimization hack help?

    - by Ian Boyd
    i'm looking over a document that describes various techniques to improve performance of Lua script code, and i'm shocked that such tricks would be required. (Although i'm quoting Lua, i've seen similar hacks in Javascript). Why would this optimization be required: For instance, the code for i = 1, 1000000 do local x = math.sin(i) end runs 30% slower than this one: local sin = math.sin for i = 1, 1000000 do local x = sin(i) end They're re-declaring sin function locally. Why would this be helpful? It's the job of the compiler to do that anyway. Why is the programmer having to do the compiler's job? i've seen similar things in Javascript; and so obviously there must be a very good reason why the interpreting compiler isn't doing its job. What is it? i see it repeatedly in the Lua environment i'm fiddling in; people redeclaring variables as local: local strfind = strfind local strlen = strlen local gsub = gsub local pairs = pairs local ipairs = ipairs local type = type local tinsert = tinsert local tremove = tremove local unpack = unpack local max = max local min = min local floor = floor local ceil = ceil local loadstring = loadstring local tostring = tostring local setmetatable = setmetatable local getmetatable = getmetatable local format = format local sin = math.sin What is going on here that people have to do the work of the compiler? Is the compiler confused by how to find format? Why is this an issue that a programmer has to deal with? Why would this not have been taken care of in 1993? i also seem to have hit a logical paradox: Optimizatin should not be done without profiling Lua has no ability to be profiled Lua should not be optimized

  • Optimization of time-varying parameters

    - by brama
    I need to find an optimal set of "n" parameter values that minimize an objective function (a 2-hr simulation of a system). I have looked at genetic algorithm and simulated annealing methods, but was wondering if there are any better algorithms and guidance on their merits and limitations. With the above optimization methods I can find the optimal parameter values that hold true for the entire simulation duration. Incase, I want to find the optimal "time varying" parameter values (parameter values change with time during the 2-hr simulation), are there any methods/ideas other than making each time varying parameter value a variable to optimize? Any thoughts?
