  • PHP array include performance

    - by tau
    What type of performance hit can I expect if I include a huge PHP array? For example, lets say I have a 1GB PHP array in "data.php" that looks like $data = array( //1GB worth of data ) If I include that huge "data.php" file on "header.php", how will it affect the performance of "header.php" when it executes? Thanks!

  • Tools to work with App Engine data dumps

    - by Thilo
    Using the bulkloader.py utility you can download all data from your application's Datastore. It is not obvious how the data is stored, however. From the looks of it, you get a SQLite file with all data in binary format in a single table: sqlite> .tables bulkloader_database_signature result sqlite> .schema result CREATE TABLE result ( id BLOB primary key, value BLOB not null, sort_key BLOB); Are there any tools to work with this data?

  • How to approach performance issues?

    - by jess
    Hi, We are developing a client-server desktop application(winforms with sql server 2008, using LINQ-SQL).We are now finding many issues related to performance.These relate to querying too much data with LINQ , bad database design,not much caching etc.What do you suggest,we should do - how to go about solving these performance issues? One thing,I am doing is doing sql profiling,and trying to fix some queries.As far caching is concerned,we have static lists.But,how to keep them updated,we don't have any server side implementation.So,these lists can be stale,if someone changes data. regards

  • What simple techniques do you use to improve performance?

    - by Cristian
    I'm talking about the way we write simple routines in order to improve performance without making your code harder to read... for instance, this is the typical for we learned: for(int i = 0; i < collection.length(); i++ ){ // stuff here } But, I usually do this when a foreach is not applicable: for(int i = 0, j = collection.length(); i < j; i++ ){ // stuff here } I think this is a better approach since it will call the length method once only... my girlfriend says it's cryptic though. Is there any other simple trick you use on your own developments?

  • Performance of "returning" from a Try block

    - by Mystagogue
    Exception handling on Windows boxes (at least for C++) takes a performance hit if you exit a try block prematurely (such as executing a return statement) the same as if an exception were thrown. But what about C#? Is there a performance hit for returning prematuraly from a try block, whether through a return statement or break statement?

  • jquery tools - tabs mouseover - 2nd.

    - by New_user
    I use this tool to show text when moving the mouse over the pix: http://flowplayer.org/tools/demos/tabs/mouseover.htm Does anybody have an idea how to force that the "context" of the second pic is shown when opening the demo-page instead of the context of the first pic (default)? Thanks for any help!

  • CVS tools for repo monitoring on windows?

    - by Bjorn J
    I sometime use the very simple but effective svncommitmonitor, http://tools.tortoisesvn.net/CommitMonitor to monitor activity. It's easy to see in the sys tray on a windows box and I've become used to it by now. So, is there a similar/identical tool for CVS. Some googling and to my surprise I couldn't find one. Any tips?

  • Java marshaller performance

    - by cbz
    Hi, I've used JAXB Marshaller as well as my own marshaller for marshalling pure java bean objects into XML. It has been observed that both of them require almost same time to marshal. The performance is not acceptable and needs to be improved. What are possible ways where we can improve performance of marshaller? Like threading?

  • mysql datetime performance

    - by praksant
    Hi, since in mysql datetime field is represented as string (i'm not sure how it works internally), wouldn't be from performance point of view faster to store date as unix timestamp? I don't need to use any mysql native date functions, i'm going for performance of sorting and selecting data. if there was an index for that column, would be difference between int and datetime? Thank you

  • Is Java much harder to "tweak" for performance compared with C/C++?

    - by user997112
    Does the "magic" of the JVM hinder the influence a programmer has over micro-optimisations in Java? I recently read in C++ sometimes the ordering of the data members can provide optimizations (granted, in the microsecond environment) and I presumed a programmer's hands are tied when it comes to squeezing performance from Java? I appreciate a decent algorithm provides greater speed-gains, but once you have the correct algorithm is Java harder to tweak due to the JVM control? If not, could people give examples of what tricks you can use in Java (besides simple compiler flags).

  • Is slower performance, of programming languages, really, a bad thing?

    - by Emanuil
    Here's how I see it. There's machine code and it's all that computers needs in order to run something. Computers don't care about programming languages. It doesn't matter to them whether the machine code comes from Perl, Python or PHP. Programming languages don't serve computers. They serve programmers. Some programming languages run slower than others but that's not necessarily because there is something wrong with them. In many cases, it's because they do more things that programmers would otherwise have to do (i.e. memory management) and by doing these things, they are better in what they are supposed to do - serve programmers. So, is slower performance, of programming languages, really, a bad thing?

  • How does Android emulator performance compare to real device performance?

    - by uj2
    I'm looking into writing an Android game, tough I don't curerntly own an Android device. For those of you who own a device, how does the performance on the emulator relate to real device performance? I'm especially interested in graphics related tasks. This obviously depends on both the machine running the emulator, and the specific device in question, but I'm talking rough numbers here. This question is a duplicate, but since that post is heavily outdated, I figured it's irrelevant by now.

  • JVM performance test suite

    - by pierr
    Hi, I have just ported phoneME to our MIPS platform. I feel it runs not that fast; however, is there any performance test suite I can run against to get some quantitative measurement of the performance? I might need to pick some weak points for optimization. In addition, what are common criterions used to evalute a JVM ?

  • Combining two UPDATE Commands - Performance ?

    - by Johannes
    If I want to update two rows in a MySQL table, using the following two command: UPDATE table SET Col = Value1 WHERE ID = ID1 UPDATE table SET Col = Value2 WHERE ID = ID2` I usually combine them into one command, so that I do not to have to contact the MySQL server twice from my C client: UPDATE table SET Col = IF( ID = ID1 , Value1 , Value2) WHERE ID=ID1 OR ID=ID2 Is this really a performance gain? Background Information: I am using a custom made fully C written high-performance heavily loaded webserver.

  • Project Performance Evaluation and Finding Weak Areas

    - by pramodc84
    I'm working in J2EE web project, which has lots of Java, SQL scripts, JS, AJAX stuff. Its been 5 years for project still running fine. I have assigned with work of performance evaluation on the project as there might be some memory usage issues, DB fetching logic delays and other similar weak performance areas. From where should I begin? Any best practices to make project better?
