I have two practically identical Debian-testing systems installed on two harddrives on the same machine. I've compiled Postgres 8.0.3 with exactly the same options on both. Both HDD use the same kernel, have DMA enabled and so on. I have the same database and web applications installed in both systems. However, one application is for some weird reason taking a serious performance hit on certain pages. There are some intensive joins and selects there, but somehow one install manages a couple of seconds and the other takes about 10. Any ideas? I've tried copying Postgres and the repository over from the good install, it does the same thing. Does this suggest that it's not a Postgres issue? ---------------------------(end of broadcast)--------------------------- TIP 5: don't forget to increase your free space map settings
