Hello,Are you using a HT processor and if so are you running the SMP kernel??
I am trying to figure out the maximum capacity of concurrent SIP users(SIP to Zap T1 channels) on my asterisk system. I assume that the processor/RAM is the weakest link in the chain in terms of capacity right now.
* see my configuration below
Right now with 18 concurrent users on SIP phones going out through Zaptel T1 channels I get an average of a 0.30 load average and 25% of my total RAM is in use. One of the things I noticed is that the 1 second load average may spike up to 0.90 and then go back down to 0.10 and the CPU idle will go from 100% to 0% every few seconds. I never have any iowait so I know nothing is getting backlogged.
With my current equipment in this machine could I conclude that I can reliably expect to have 60 cuncurrent SIP-to-Zap users on my system?
Configuration: Asus 800MHz bus Motherboard P4 2.8GHz with 800MHz bus 2GB DDR400 RAM SCSI RAID 10 (4 drives mirrored and spanned) one Digium T400 card 3 T1s plugged in RedHat linux 9 no Xwindows or unnecessary services running
Any help would be appreciated,

IIRC the load avereage is added together for each CPU so if a single CPU system had a max load average of 1.0 then a dual CPU system would have a max load avaerage of 2.0 and so on.. So if you are using HT and the SMP kernel then you should probably half your load average to get it back to a common base, and that would mean you have an actual load average of 0.15.. Or am I completely wrong here!?!?
Later..
