Ivan Voras: > [I just skimmed this thread - did you increase the number of WAL logs to > something very large, like 128?] Yes, I tried even more. I will be writing data quite constantly in the real scenario later. So I wonder if increasing WAL logs will have a positive effect or not: AFAIK when I increase it, the duration after the max is hit will be longer then (which is not acceptable in my case). Could anyone confirm if I got it right?
