Adriano The test is quite CPU bound, the disk I/O was relatively low (and running on a FusionIO SSD). I do think that this is an AMD/Windows issue, too. It was just for testing. And Doychin is right about the NUMA-architecture, so the (total of) 32 cores are distributed into 4 NUMA nodes. That could explain the behaviour that one NUMA node is preferred to minimize memory sharing. The dual processor Opteron has two memory banks, which is again optimally equipped with an equal number of memory modules - maybe to satisfy each NUMA node with its own memory bank. I wonder, though, if this is optimal for, say, super server with many different DB's. In that case the optimal solution - I think - is to have one DB per core, if possible, and not try to keep the threads together on one NUMA node. But still that is not a FB problem.

[Firebird-devel] True SMP support in SuperClassic and V3
Hi all, I have been doing a lot of testing on a monster Windows server so that we can move from a Solaris 2.1.3 build (thanks Paul) to 2.5 on preferably Windows, or perhaps Linux. The box has 8 processors, each with 8 cores. These are arranged into 4 NUMA nodes, each with 2 processors. Windows reports 4 processors (i.e. each NUMA node is seen as one processor) , each with 16 cores. 128GB RAM, Windows 2008 R2. Firebird Version: WI-V2.5.2.26539 Firebird 2.5 My concern is that in this article: http://www.firebirdsql.org/manual/qsg25-classic-or-super.html it is stated that SuperServer uses one processor (unless CPUAffinityMask is changed) and that Classic and SuperClassic ignore CPUAffinityMask, and use all processors. When running under load (150+ busy connections) SuperClassic clearly uses only one NUMA node (threads are spread across 16 cores), while Classic is spread evenly across all 64 cores. CPUAffinityMask makes no difference (as stated in the docs). How is this going to run in V3? Will we see full use of all cores on all processors, or will the behaviour be as in SuperClassic. Is this a machine architectural issue? i.e. the NUMA node architecture makes it a little more difficult for one NUMA node to access the memory 'allocated' to another NUMA node? which implies that V3's shared cache may be restricted to one node, and not spread across all nodes?

Re: [Firebird-devel] True SMP support in SuperClassic and V3
I might have a theory on that subject. With HT you share the same execution blocks among two pipelines (meaning you are trying to balance twice as many threads/instructions and so on, without increasing reorder caches/registers/data and instruction caches and other important factors). On a normal PC you have threads with different profiles - media streaming, integer calculations and so on, so most tasks don`t overlap as much and you feel a big boost. With the database (or any other dedicated server for that matter), on the other hand, you have basically the same profile for all threads and you starve the CPU from certain blocks/registers, while you don`t really utilize the others. You also have some kind of synchronization between the two pipelines. When you have a single user (filling the info in the database) you don`t feel the difference because it is basically the same CPU core doing the work. I could be wrong on that one, but under ultra heavy loads I guess all those things will be noticeable. Nobody was able to explain why such big difference. Interesting that the performance was similar in both machines when loading the database with information. The huge difference only appeared when using the database.

Hi all, Thanks for the replies and comments. Vince, FB 3 snapshot is already available for download, so you can check it by yourself (and if so, please report the results here). I have V3 running on a much smaller VM, just to test if my stress tests run at all - short answer : they don't :-) The DB is a Dialect 1 with a lot of legacy rubbish. I will certainly update the tests in order to get them to run properly on V3, and will report back. The big box is earmarked as a production server, so I won't have access for long, but I will make a plan. I should be able to run both 2.5 and 3 on the same box? Vince Actually, with such heavy server, I think you can help the Project a lot with FB 3 tests. Personally, I got weird results using FB 3 in my notebook (4 cores, 2 real and 2 HT and 8GB RAM) and TPC-C tests. The same tests showed much better results (at last 10x better) in a quad core desktop (this time, 4 real cores but only 4GB RAM). Nobody was able to explain why such big difference. Interesting that the performance was similar in both machines when loading the database with information.

Re: [Firebird-devel] True SMP support in SuperClassic and V3
IA When you have a single user (filling the info in the database) you don`t IA feel the difference because it is basically the same CPU core doing the IA work. Here is more information (from my logs and memory): The LOAD was set to simulate 10 users inserting information at the same time so, there was 10 connections and 10 threads acting at the same time to fill up the DB. Some weird results also appeared when comparing FB 3 TPC-C results in the notebook. FB 3 performance was 50% worse compared to FB 2.5 SS/CS/SC. From my logs: 2.5.1 CS - TPC-C Throughput: 1390.19 tpmC 2.5.1 SC - TPC-C Throughput: 1221.92 tpmC - Affinity set to 1 2.5.1 SS - TPC-C Throughput: 1306.06 tpmC 2.5.2 CS - TPC-C Throughput: 1144.95 tpmC 2.5.2 SC - TPC-C Throughput: 1156.87 tpmC - Affinity set to 1 2.5.2 SS - TPC-C Throughput: 1358.34 tpmC 3.0 SS - TPC-C Throughput: 514.43 tpmC (SharedCache was true and SharesDatabase was false) Notebook config: Windows 7 Pro 64bits Intel Core i5 2410M 500GB Sata 7200rpm 8GB RAM I agree that in a real scenario, a notebook would not be used as a server, but I wonder why such bad performance, even when compared to FB 2.5.2 SS attached to single CPU. Curious that the LOAD process seems to not suffer from the problem. I just hope nothing similar will show up in real servers, since it would be very disappointing to the user if he moves to FB 3 expecting huge improvement and find out that it started to behave worse than FB 2.5. I plan to start a global testing campaign at FirebirdNews.org when FB 3 alpha shows up, in the hope to detect all possible bad behaviors and bugs, in the hope to speed up the release process.
