Hiya, just wondering something as have a dual (hyperthreaded) CPU setup. In top naturally shows as 4 virtual CPUS.
Basic question is in the load figures, for example on a single cpu system I would try and keep the load if possible below 1.
So on a dual/4 virtual cpu setup, whats roughly the equivalent of a decently equivalent system in terms of waiting processes (ie load), is it still a load of 1 no matter how many CPUs you have, or is a load of 2 ok (ie matches number of CPUS), as there's now 2 CPUs to take in processes twice as often if that makes sense?
TIA, just want to get a decent idea of the equivalent mark to keep load under.
The load consists of I/O wait as well as CPU ... so if you
had a busy database or web-server that has HD-I/O or
lots of network activity you'd still see a high load ...
One of our database machine's (dual-xeon) the load
is (despite SCSI-RAID) always above 3 ... :)
Hiya and thanks a lot for the replies. The main thing I guess is there's a couple of game servers on there which are more dependant on time factors in terms of response of processing and back to user maybe more than databases/webstuff, so I guess trying to find whats a good load without being overloaded if that makes sense.
