I will. I'm currently running tests with less concurrent clients (16) with exactly the same results: 64M 4213.314902 256M 4012.782820 512M 3676.840722 768M 3377.791211 1024M 2863.133965 64M again 4274.531310 I'm rerunning the tests using Greg Smith's pgbench-tools [1] to obtain a graph of each run.
