Hi all, I'm asking myself about a problem I have with a Postgresql server on FreeBSD 7.1-RELEASE. The server is overload, the disk is 100% busy with 250 write operations per second and a throuput of 6MB/s. My first idea is because of mass random access/write on the disk. But I also see the server can make 20k page fault per second. So, did you think I really have a disk contention or this high number of page fault can be a problem (and if it can, how to resolve it). Thanks, -- Nicolas Haller
