AFAICT the operative word there is "some" --- the heavily used paths should make power-of-two requests to malloc, because aset block sizes will normally be powers of two. Can you put your finger on paths that generate a significant number of non-power-of-two requests? regards, tom lane ---------------------------(end of broadcast)--------------------------- TIP 7: don't forget to increase your free space map settings
