It looks like at some point, someone here said "oh, and it looks like you're better off using large values here for 8.1.x and newer", and now everybody seems to repeat it as if it was always well-known. Are there any real benchmarks out there that we can point to? And, if you set shared_buffers to half of the available memory, won't the kernel cache duplicate more or less exactly the same data? (At least that's what people used to say around here, but I guess the kernel cache gets adapted to the fact that Postgres won't ask for the most common stuff, ie. the one in the shared buffer cache.) /* Steinar */ -- Homepage: http://www.sesse.net/
