Hi folks,
is there a general problem with raid10 performance postgresql on it?
We see very low performance on writes (2-3x slower than on less
performant servers). I wonder if it is solely problem of raid10
configuration, or if it is postgresql's thing.
Would moving WAL dir to separate disk help potentially ?
We're running centos 5.4, and server config is:
x3550 M2, xeon 4c e5530 2.4ghz , 6GB of ram
disks: ibm 300gb 2.5 SAS
raid: serveRAID M5014 SAS/SATA controller
strip size is the default 128k
thanks.
