Or are you suggesting something else? when you compute optimal shared buffers and effective cache size, these are in terms of blocksize. so if I have 16k block size, you can't compute based on default 8k blocksize. at worst, it would have to be a parameter you pass to the tuning script. ---------------------------(end of broadcast)--------------------------- TIP 7: don't forget to increase your free space map settings ---------------------------(end of broadcast)--------------------------- TIP 6: Have you searched our list archives? http://archives.postgresql.org
