Hi folks, Alexey might be referring to us as we also had some performance issues under Win2008R2 and FB 252 SS, but we started a different thread, so I might as well be wrong. Anyway we are still in the process of evaluating the impact of our resolving actions on performance. The operator company rebuilt the server from scratch and we have also changed the application logic a bit, but nothing really changed seriously on either side. We aimed to satisfy the needs and satisfaction of the client and therefore we do not want to change or have any impact on the system that might alter the performance negatively yet. We try to suspend this status quo for some time. More to come on the issue and hopefully the cause and resolution, I ask for Your patience. Regarding Alexey's support. I personally asked for Alexey's help and although we have not got into deep system analysis I must say that during the negotiating process Alexey's attitude was way superior, he was fast at reply, helpful and professional. I am sure we will be happy collaborating on other issues in the future.

We are using Windows 2008 R2 64 bits, with databases around 35 Gb, and we solved the performance problems with FB 2.5.2.

[Marius Labuschagne] We have sites running Windows 2008 R2 64bits (Xeon Quad Core E31220 @ 3.1 Ghz) , with much smaller databases (2-4GB Range), and on Firebird Super Server 2.5.2, and I can tell you that that platform is definitely much much slower in performance than just a simple I3 desktop pc with 8GB of RAM on the exact same database, running Windows 7 Pro or Windows 8 Pro, either 32- or 64-bit. I think you are very lucky Jesus that your problem was solved by 2.5.2 Example: Executing the Month-End in our application, exact same database: - On a Win 2008 R2 64-bit Xeon Machine with 8GB RAM: 55 Minutes - On a Win 7 Pro 64-bit I3 machine with 8GB RAM: 9 Minutes For that specific platform 2.5.2 has not done anything for the performance issue. I suppose we are also lucky that our Clients database is not larger than the physical RAM present at this point in time, hopefully once they do get there I will be able to convince the Client that just using a desktop computer with a standard desktop operating system, is the way to go.

In all cases when you see performance degradation at Win2008R2 and everything is smooth on Linux/Win7/etc - it is not an OS fault, it's a problem with configuration (incl. version) of Firebird and OS (incl. drivers and domain controllers), or performance problems in your own code (in 80% it's long-running transactions).

Performance problems with your own code, laughing at this, as the same problem will present itself on other platforms then as well, especially if the platforms compared is presenting the problem on the supposedly more superior platform.

Hello, AFAIK, the parameter DefaultDbCachePages is intended for newly created databases as default size of cache pages. It doesn't have effect on existing databases where its own setting is used. Every database can have own setting about count of cache pages. The DefaultDbCachePages parameter in firebird.conf applies when page buffers of the database is set to 0. It seems to be still not solving this problem using by FileSystemCacheSize. What else can I test? I haven't followed the entire thread, but first I would rule out I/O problems like faulty RAID controllers etc. In a particular case I was called, although a high-end server in that case, performance was worse than on an oldish laptop. Then there are various tuning/optimizations techniques and settings, which I usually discuss and go through at customer sites. Page size, page buffers, hash slots, increasing RAM usage for the sorting module etc. Once the tuning/configuration side is exhausted, SQL tuning is probably the most important thing. At least from my experience. For sure, I would move away from SuperServer to Classic or SuperClassic to get an overall increase in CPU utilization in a multi-user environment. Although e.g. gbak is still bound to a single core. -- With regards, Thomas Steinmaurer http://www.upscene.com/ Professional Tools and Services for Firebird FB TraceManager, IB LogManager, Database Health Check, Tuning etc. 22.01.2014 15:05 - Hugo Eyng hugoe...@msn.com Try changing values for DefaultDbCachePages Em 21/01/2014 18:40, Roland Turcan escreveu: I have tried to change this parameter (actually =20), but I don't see any change.

Hi! CristalDiskMark: Seq 468 MB/s Read161 MB/s Write(Ten times faster than a notebook vostro 1510 intel core 2 duo 1.8ghz) Sequential Disk performance is completely irrelevant to a database workload which is 99% random I/O.

Maybe your problem is that you buy a internet server from dell, not a database server! What is the diference? Internet servers from Dell does not have a disk controller WITH physical cache. Run CrystalDiskMark or other disk benckmark on this computer and in another desktop computer. If it is slow you need to replace your disk controller. Also read from Helen sayd.
