We had to move from a old * server to a new one in a hurry (hardware
failure). The old server was a dual pentium 700 with 512MB ram running
fedora core 2, the new one is a single 3GHz Pentium with 1gb ram.
The same number of people are connected to the new server as the old,
the same number of inbound calls to the isdn30 etc (on average 20
calls active at any time (SIP and ZAP)). Basically, just a server
swapout.
I must be reading top wrong, because the old server had a idle of
approx 30%, whereas the new server is
top - 13:35:21 up 12 days, 23:57, 1 user, load average: 7.11, 7.20,
7.21
Tasks: 98 total, 9 running, 89 sleeping, 0 stopped, 0 zombie
Cpu(s): 99.0% us, 1.0% sy, 0.0% ni, 0.0% id, 0.0% wa, 0.0% hi,
0.0% si
Mem: 1034640k total, 144792k used, 889848k free, 21952k buffers
Swap: 2031608k total, 0k used, 2031608k free, 61248k cached
Notice the 99.0% us. This fluctuates between 80 and 99%.
The other difference is that the new server is on cvs-head as of today
- I did say that it was an emergency :) whereas the old server was
cvs-head from june sometime.
Is it just me, or is there a problem ?
Well, I suppose it depends on what's using all that CPU -- you leave
that part out.
Assuming it's asterisk threads causing the 100% cpu usage, and the load
average of 7, then, yes, that's a lot of CPU.
But, you could have some other program/processes doing that, and if
they're batch processes (they're clearly not niced), they may end up
with a lower dynamic priority and not affect asterisk too much.
