[Asterisk-Users] I guess my server capacity is ok

I have seen this same type of stats on the list a couple of times now and
wanted to share a thought. I am not a linux expert by any means, but in the
windows world a 100% CPU idle means the percentage of CPU that is currently
ideling. Basicly if I take all the process in the task manager and add up
the percentages it should equal 100 and "System Idle" general takes up the
left overs. Reaing the CPU stats above it looks like 86.2% of the CPU is
currently unused, A good thin in my book. To test my theroy I loaded up an *
server and with no calls there was 100% id the more calls the lower the
number got.
Again just thoughts from a non-linux guru.
