  • Does use of simple shaders improve performace/battery life?

    - by Miro
    I'm making OpenGL game for Android. Till now i've used only fixed function pipeline, but i'm rendering simple things. Fixed function pipeline includes a lot of stuff i don't need. So i'm thinking about implementing shaders in my game to simplify OpenGL pipeline if it can make better performance. Better performance = better battery life, unless fps is limited by software limit, not hardware power.

  • Slow gvfs Samba Performance

    - by Wolfgang
    if I use/acces a Samba Share using Nautilus or manually using "gvfs-mount smb://SERVER-IP/Share" I get a poor Performance, only about 7 mb/s on my 100 Mbit Network. If I access the same Share on Windows I get Fullspeed 100 Mbit (About 11 mb/s), also if I mount using sudo mount -t cifs //SERVER-IP/Share /mountpount which uses cifs instead of gvfs I get fullspeed too, so can anyone tell me if there is a Performance Problem/Bug in gvfs or how gvfs is using SMB Shares differerently ? I tested read Perfomance (From my Network Samba Share) with multiples files and always, the cifs-Version is fullspeed and the GVFS-Version has some mb/s less. After some research I found some tips to optimize the Samba Settings of my Ubuntu Installation and some network tuning tips, but as the CIFS mounted share gets the full Network Speed I don't believe its that kind of problem.

  • Swiss Re increases data warehouse performance and deploys in record time

    - by KLaker
    Great information on yet another data warehouse deployment on Exadata. A little background on Swiss Re: In 2002, Swiss Re established a data warehouse for its client markets and products to gather reinsurance information across all organizational units into an integrated structure. The data warehouse provided the basis for reporting at the group level with drill-down capability to individual contracts, while facilitating application integration and data exchange by using common data standards. Initially focusing on property and casualty reinsurance information only, it now includes life and health reinsurance, insurance, and nonlife insurance information. Key highlights of the benefits that Swiss Re achieved by using Exadata: Reduced the time to feed the data warehouse and generate data marts by 58% Reduced average runtime by 24% for standard reports comfortably loading two data warehouse refreshes per day with incremental feeds Freed up technical experts by significantly minimizing time spent on tuning activities Most importantly this was one of the fastest project deployments in Swiss Re's history. They went from installation to production in just four months! What is truly surprising is the that it only took two weeks between power-on to testing the machine with full data volumes! Business teams at Swiss Re are now able to fully exploit up-to-date analytics across property, casualty, life, health insurance, and reinsurance lines to identify successful products. These points are highlighted in the following quotes from Dr. Stephan Gutzwiller, Head of Data Warehouse Services at Swiss Re:  "We were operating a complete Oracle stack, including servers, storage area network, operating systems, and databases that was well optimized and delivered very good performance over an extended period of time. When a hardware replacement was scheduled for 2012, Oracle Exadata was a natural choice—and the performance increase was impressive. It enabled us to deliver analytics to our internal customers faster, without hiring more IT staff" “The high quality data that is readily available with Oracle Exadata gives us the insight and agility we need to cater to client needs. We also can continue re-engineering to keep up with the increasing demand without having to grow the organization. This combination creates excellent business value.” Our full press release is available here: http://www.oracle.com/us/corporate/customers/customersearch/swiss-re-1-exadata-ss-2050409.html.

  • Why profile applications using AOP?

    - by Vance
    When tuning performance in a web application, I am looking for good and light-weight performance profiling tools to measure the execution time for each method. I know that the easiest profiling method is to log the start time and end time for each method, but I see more and more people using AOP to profile (add @profiled before each method). What's the benefit of AOP profiling compared to the common "log" way? Thanks in advance Vance

  • Play audio in javascript with a good performance

    - by João
    I'm developing a browser game where the player can shoot. Everytime he shoots it play a sound. Currently i'm using this code to play sounds in JavaScript: var audio = document.createElement("audio"); audio.src = "my_sound.mp3"; audio.play(); I'm worried about performance here. Will 10 simultaneous sounds impact my game performance too much? Will all audio objects stay in memory even after they are played?

  • Real performance of node.js

    - by uther.lightbringer
    I've got a question concerning node.js performance. There is quite lot of "benchmarks" and a lot of fuss about great performance of node.js. But how does it stand in real world? Not just process empty request at high speed. If someone could try to compare this scenario: Java (or equivalent) server running an application with complex business logic between receiving request and sending response. How would node.js deal with it? If there was need for a lot of JavaScript processing on server side, is node.js really so fast that it can execute JavaScript, and stand a chance against more heavyveight competitors?

  • Quick Tip - Speed a Slow Restore from the Transaction Log

    - by KKline
    Here's a quick tip for you: During some restore operations on Microsoft SQL Server, the transaction log redo step might be taking an unusually long time. Depending somewhat on the version and edition of SQL Server you've installed, you may be able to increase performance by tinkering with the readahead performance for the redo operations. To do this, you should use the MAXTRANSFERSIZE parameter of the RESTORE statement. For example, if you set MAXTRANSFERSIZE=1048576, it'll use 1MB buffers. If you...(read more)

  • How to perform a detailed and quick 3D performance test

    - by gsedej
    I am wondering how to quickly test performance of my 3D graphics. Since glxgears is not benchmark what should I use. Also glxgears sometimes stuck at 60FPS, you cannot even compare before/after driver update (e.g. adding xorg-edgers PPA). Even glxgears doesn't really work out of box. One possibility is screensavers, but you can't see FPS. I am also not willing to install 600MB nexuiz, specially if I am running on Live-CD. Other 3D games are also very big... Unigine tests are too demanding for opensource drivers (problems with too low OpenGL and probably texture compression (S3TC...)). I would also like to test OpenGL 2.x extentions. How to quickly test your 3D performance?

  • What arguments can I use to "sell" the BDD concept to a team reluctant to adopt it?

    - by S.Robins
    I am a bit of a vocal proponent of the BDD methodology. I've been applying BDD for a couple of years now, and have adopted StoryQ as my framework of choice when developing DotNet applications. Even though I have been unit testing for many years, and had previously shifted to a test-first approach, I've found that I get much more value out of using a BDD framework, because my tests capture the intent of the requirements in relatively clear English within my code, and because my tests can execute multiple assertions without ending the test halfway through - meaning I can see which specific assertions pass/fail at a glance without debugging to prove it. This has really been the tip of the iceberg for me, as I've also noticed that I am able to debug both test and implementation code in a more targeted manner, with the result that my productivity has grown significantly, and that I can more easily determine where a failure occurs if a problem happens to make it all the way to the integration build due to the output that makes its way into the build logs. Further, the StoryQ api has a lovely fluent syntax that is easy to learn and which can be applied in an extraordinary number of ways, requiring no external dependencies in order to use it. So with all of these benefits, you would think it an easy to introduce the concept to the rest of the team. Unfortunately, the other team members are reluctant to even look at StoryQ to evaluate it properly (let alone entertain the idea of applying BDD), and have convinced each other to try and remove a number of StoryQ elements from our own core testing framework, even though they originally supported the use of StoryQ, and that it doesn't impact on any other part of our testing system. Doing so would end up increasing my workload significantly overall and really goes against the grain, as I am convinced through practical experience that it is a better way to work in a test-first manner in our particular working environment, and can only lead to greater improvements in the quality of our software, given I've found it easier to stick with test first using BDD. So the question really comes down to the following: What arguments can I use to really drive the point home that it would be better to use StoryQ, or at the very least apply the BDD methodology? Can you point me to any anecdotal evidence that I can use to support my argument to adopt BDD as our standard method of choice? What counter arguments can you think of that could suggest that my wish to convert the team efforts to BDD might be in error? Yes, I'm happy to be proven wrong provided the argument is a sound one. NOTE: I am not advocating that we rewrite our tests in their entirety, but rather to simply start working in a different manner for all future testing work.

  • How to improve Unity Performance?

    - by Wolter Hellmund
    I installed ubuntu netbook edition on my netbook* expecting to get the best performance out of it, but apparently, that didn't turn out. Unity is a bit slow on it, and when I click on Files and folders it takes a while to load the respective interface and the bar at the top disappears and then loads in. Is this expected? Is there anything I can do to improve the performance? Is this problem specific to my netbook? *Netbook info: Acer - Aspire One 1.6 GHz Intel Atom Processor 1 GB RAM Memory Intel GMA 950 graphics card

  • Optimus Bumblebee Performance

    - by Chance
    After installing Ubuntu 12.04 and Bumblebee, I tested out the performance of the Nvidia card using Minecraft and a few other games. I've noticed it to be way slower than it was on Windows 7. Is this normal? I'm using the GT 630m. From what I've read online, nobody has said it to be slower than Windows. I'm just really curious because I want to use Linux so much more than Windows, but if I don't get the same performance I feel really picky. The Nvidia card is still faster than my Intel graphics on Ubuntu, but it's not as fast as it was for my on Windows. I get 60 - 80 fps on Minecraft on windows, while I get 28 - 48 fps on Ubuntu. Any Ideas why? Thanks so much!

  • Design Patterns for SSIS Performance (Presentation)

    Here are the slides from my session (Design patterns for SSIS Performance) presented at SQLBits VI in London last Friday. Slides - Design Patterns for SSIS Performance - Darren Green.pptx (86KB) It was an interesting session, with some very kind feedback, especially considering I woke up on Friday without a voice. The remnants of a near fatal case on man flu rather than any overindulgence the night before I assure you. With much coughing, I tried to turn the off the radio mike during the worst, and an interesting vocal range, we got through it and it seemed to be well received. Thanks to all those who attended.
