  • Will unity stop being a plugin for Compiz?

    - by Murphy1138
    I ask this as with the Unity Desktop running , when I try any games with my Ubuntu 12.04.1 I get so much frame rate drop with Unity and Compiz. If I switch to Gnome-Classic which uses mutter, I get a vast boost in performance. My system is an 8 core AMD with a Nvidia 460 SE that can play anything I chuck at it in Windows and I'm using the latest Nvidia drivers, but even simple games like the humble bundle gets serious lag with Unity and the only cause of this can be compiz (what I can guess). When Steam come to Ubuntu, how will this performance loss be addressed?

  • How to remove the graphical user interface?

    - by Praveen Kumar
    Ok my question is that, I want to run a heavy application, on a Virtual Machine (VirtualBox) with just 2 GB RAM (Windows 7 32Bit Host has 4 GB, 3.5 GB effective). Initially I thought of installing Ubuntu Server 12.04.1, which doesn't come with a GUI, so I thought it would be efficient in performance, but I have only Ubuntu 12.04 Desktop. My question is, is it possible to remove the GUI parts in Ubuntu 12.04 Desktop (Not Server), keeping only the core OS, after installation in a virtual machine? Or, is there anyway to improve the performance of the OS? If you need more information, I am ready to provide. I don't want the GUI or anything, even a small terminal window is fine for me, I can access files through FTP.

  • What are the benefits of archiving?

    - by HappyDeveloper
    I always see sites that only keeps fresh content on the home or subsections, and the rest of the content is kept in a separate section called 'archive'. Recently I have also heard that NoSQL DB's like MongoDB are good for archiving (which makes me think this is related to performance) So why do sites archive their content? What's the benefit over say, a simple paginator through which you could reach all the content? Is archiving done for performance? Or SEO? Or just user experience?

  • Redgate ANTS Performance Profiler

    - by Jon Canning
    Seemingly forever I've been working on a business idea, it's a REST API delivering content to mobiles, and I've never really had much idea about its performance. Yes, I have a suite of unit tests and integration tests, but these only tell me that it works, not how well it works. I was also about to embark on a major refactor, swapping the database from MongoDB to RavenDB, and was curious to see if that impacted performance at all, so I needed a profiler that supported IIS Express that I can run my integration tests against, and Google gave me:   http://www.red-gate.com/supportcenter/content/ANTS_Performance_Profiler/help/7.4/app_iise   Excellent. Following the above guide an instance of IIS Express and is launched, as is Internet Explorer. The latter eventually becomes annoying, I would like to decide whether I want a browser opened, but thankfully the guide is wrong in that it can be closed and profiling will continue. So I ran my tests, stopped profiling, and was presented with a call tree listing the endpoints called and allowing me to drill down to the source code beneath.     Although useful and fascinating this wasn't what I was expecting to see, I was after the method timings from the entire test suite. Switching Show to Methods Grid presented me with a list of my methods, with the slowest lit up in red at the top. Marvellous.     I did find that if you switch to Methods Grid before Call tree has loaded, you do not get the red warnings.   StructureMap was very busy, and next on the list was a request filter that I didn't expect to be so overworked. Highlighting it, the source code was presented to me in the bottom window with timings and a nice red indicator to show me where to look. Oh horror, that reflection hack I put in months ago, I'd forgotten all about it. It was calling Validate<T>() which in turn was resolving a validator from StructureMap. Note to self, use //TODO: when leaving smelly code lying around.     Before refactoring, remember to Save Profile Results from the File menu. Annoyingly you are not prompted to save your results when exiting, and using Save Project will only leave you thankful that you have version control and can go back in time to run your tests again.   Having implemented StructureMap’s ForGenericType, I ran my tests again and:     Win, thankyou ANTS (What does ANTS stand for BTW?)   There's definitely room in my toolbox for a profiler; what started out as idle curiosity actually solved a potential problem. When presented with a new codebase I can see enormous benefit from getting an overview of the pipeline from the call tree before drilling into the code, and as a sanity check before release it gives a little more reassurance that you've done your best, and shows you exactly where to look if you haven’t.   Next I’m going to profile a load test.

  • CDN for site with target market in Australia

    - by Jae Choi
    I was told that http://www.edgecast.com/ is very good CDN provider for Australian market. I have a cloud server based in Sydney Australia but was wondering whether it's even worth getting cdn as my target market is only Australia based also. Would I see any performance gain if I use above CDN services or would this be more for sites that target international visitors? I have Apache installed in our server but I would like to install Nginx. Would I see much more gain in performance on this change than CDN or should I go for both as they are all beneficial?

  • SQL Server v.Next (Denali) : Changes to performance counters

    - by AaronBertrand
    In a previous post about changed system objects in Denali , I talked about the changes to memory-related DMVs due to underlying changes in the memory manager. The SQLOS team has posted a great introduction to these changes , and they plan to post more details in future posts. In the meantime, and due to a question yesterday from Tom LaRock ( blog | twitter ): ...I thought I would tell you about some performance counters that have changed between SQL Server 2008 R2 and Denali - most of which involve...(read more)

  • Compiling vs using pre-built binaries performance?

    - by Nick Rosencrantz
    Will performance be better (quicker) if I manually compile the source for a software component for the actual machine that it will be used on, compared to if the source was compiled on another platform perhaps for many different architectures? I got some good results compiling source that I downloaded and I wonder whether this was due to compiling it instead of downloading a pre-compiled binary which is often the case with software updates.

  • Compilable modern alternatives to C/C++

    - by Jeremy French
    I am considering writing a new software product. Performance will be critical, so I am wary of using an interpreted or language or one that uses a emulation layer (read java). Which leads me to thinking of using C (or C++) however these are both rather long in the tooth. I haven't used either for a long time. I figure in the last 20 years someone should have created something which is reasonably popular and is nice to code in and is complied. What more modern alternatives are there to C for writing high performance code compiled code? edit in response to comments If C++ is a different beast than it was 15 years ago, I would consider it, I guess I had an assumption that it had some inherent problems. Parallelisation would be important, but probably not across multiple machines.

  • Improving the performance of JDeveloper11g (part 2) and JVMs in general

    - by asantaga
    Just received an email from one of our JVM developers who read my blog entry on Performance tuning JDeveloper11g and he's confirmed that all of the above parameters are totally supported :-) He's also provided a description of the parameters so we can learn what magic is actually being applied. - -XX:+AggressiveOpts -- this enables the latest and greatest JVM optimizations. It will likely help most Java applications. It's fully supported. The downside of it is that because it has the latest and greatest optimizations, there is some small probability that it may not offer as good of an experience. As those features enabled with this command line option have "matured", they are made the default in a future JDK release. So, you can think of this command line option as the place where the newest optimizations get introduced. Some time later they are moved out from under AggressiveOpts to become default behavior. -XX:+OptimizeStringConcat -- only works with the -server JVM. It may be enabled by the default in a future JDK 7 update release. This option delays the construction of a StringBuilder/StringBuffer and attempts to avoid re-sizing the underlying char[] by attempting to detect the size of the char[] to allocate based on what's being appended to the StringBuilder/StringBuffer. -XX:+UseStringCache -- I would not suggest using this unless you knew that JDeveloper allocated the same string over and over again. And, the string that's allocated over and over again is one of the first 100,000 allocated strings. In short, I'd recommend against using it. And, in fact, in Java 7 (currently) does not include this feature. -XX:+UseCompressedOops -- applicable to 64-bit JVMs. And, if you're using a 64-bit JVM, I'd suggest you use it. It's auto enabled in JDK 7 64-bit JVMs and later JDK 6 64-bit JVMs enable it by default too. -XX:+UseGCOverheadLimit -- by default this option is already enabled. One other command line option to consider is -XX:+TieredCompilation for a JDK 6 Update 25 or later, or JDK 7. This gives you the startup of a -client JVM and the peak performance of a -server JVM. Awesome-ness!  Finally, Charlies also pointed out to me a "new" book he's just published where he goes into the details of JVM tuning, a must for all Fusion Middleware tuning exercises..  (click the book)  Thanks Charlie!

  • Does 3d modeling software *choice used during asset creation affect performance at runtime

    - by user134143
    Does software used to create 3d assets (for game development specifically) have an impact on the efficiency of the program? In other words, is it possible to reduce the operating footprint of an application merely by utilizing alternative development software during production of 3d assets? If you use two different applications to create a 3 dimensional image of a box, can one of them result in better performance if aspects of the image are identical? I am attempting to get the information I need without causing unnecessary debate over specific software choice.

  • Load Balance and Parallel Performance

    Load balancing an application workload among threads is critical to performance. However, achieving perfect load balance is non-trivial, and it depends on the parallelism within the application, workload, the number of threads, load balancing policy, and the threading implementation.

  • How to Structure Bonuses for Software Developers?

    - by campbelt
    I am a software developer, and have been asked to define a bonus structure for myself by recommending the metrics that will determine my bonus. I think, once I have defined this bonus structure, there is a decent chance that it will end up applying it to other members of my department. So, for personal and professional reasons, I want to try to get this right :) I am wondering, what do you guys think are fair and accurate measurements of a software developer's performance? And, if you are a developer or manager of developers, what metrics does your company use to measure developer performance?

  • Best practice on Linux servers and CPU/power throttling?

    - by Valentin
    I am running a couple of Debian 6 (2.6.32) and 7 (3.2) Linux servers and all of them have energy saving settings enabled in their BIOS. Furthermore Linux shows that the CPUs are throttled if the servers are idling. I wonder if this could cause any harm - could there be e.g. performance impacts because Linux would not be able to handle throttling correctly? Is there a best practice for Linux servers and power/CPU throttling? Do you guys switch your energy profiles to "performance" or do you leave both the BIOS and the OS with their default settings? The reason I am asking is that I encountered several performance issues on physical Dell servers although all values (CPU/load, memory, I/O, network etc.) seemed to be normal. After changing the BIOS power settings to "performance" in those specific cases, I was able to get rid of the performance issues.

  • How should I account for the GC when building games with Unity?

    - by Eonil
    *As far as I know, Unity3D for iOS is based on the Mono runtime and Mono has only generational mark & sweep GC. This GC system can't avoid GC time which stops game system. Instance pooling can reduce this but not completely, because we can't control instantiation happens in the CLR's base class library. Those hidden small and frequent instances will raise un-deterministic GC time eventually. Forcing complete GC periodically will degrade performance greatly (can Mono force complete GC, actually?) So, how can I avoid this GC time when using Unity3D without huge performance degrade?
