IA>> When you have a single user (filling the info in the database) you don`t

CHC> Here is more information (from my logs and memory):

CHC> The LOAD was set to simulate 10 users inserting information at the same
CHC> time so, there was 10 connections and 10 threads acting at the same
CHC> time to fill up the DB.

CHC> Some weird results also appeared when comparing FB 3 TPC-C results in
CHC> the notebook. FB 3 performance was 50% worse compared to FB 2.5
CHC> SS/CS/SC. From my logs:

CHC> 2.5.1 CS - TPC-C Throughput: 1390.19 tpmC
CHC> 2.5.1 SC - TPC-C Throughput: 1221.92 tpmC <- Affinity set to 1
CHC> 2.5.1 SS - TPC-C Throughput: 1306.06 tpmC

CHC> 2.5.2 CS - TPC-C Throughput: 1144.95 tpmC
CHC> 2.5.2 SC - TPC-C Throughput: 1156.87 tpmC <- Affinity set to 1
CHC> 2.5.2 SS - TPC-C Throughput: 1358.34 tpmC

CHC> 3.0 SS - TPC-C Throughput: 514.43 tpmC (SharedCache was true and 
SharesDatabase was false)
