We recently upgraded from php 4.3.10 to 5.1.2, and the %system time has
skyrocketed:
Cpu(s): 42.8% us, 43.6% sy, 0.0% ni, 11.3% id, 2.2% wa, 0.2% hi, 0.0% si
Mem: 8312844k total, 7566168k used, 746676k free, 22356k buffers
Swap: 2040244k total, 520k used, 2039724k free, 6920384k cached
it used to be around 5% to 10%. The server is a quad-xeon dell pe 6650
running CentOS 4.2 with 8G of RAM running pg 8.1.1.
How can I determine what is causing such high system load? it seems to
have immediately jumped with the php upgrade.
thanks,
