Having upgraded to 2.6.18 fairly recently, I am *very* interested in
what caused the throughput to drop in 2.6.18? I haven't done any
benchmarking on my system to know if it affected my usage pattern
negatively, but I am curious if anyone knows why this happened?
I think you're reading the results backwards. PostgreSQL throughput
increased, not decreased, by the upgrade.
