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 misread the graph. PostgreSQL 8.2 seems to be approximately 20% faster with kernel 2.6.18 on the platforms tested (and using tweakers.net benchmark). -- Guillaume
