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.
