Anyone seen statistics like this before? These are from a web server
that I can't get access to, but I had someone send me a couple of
statistics. I'm not a system administrator, but the curious thing to
me is the runq spikes up, but the %idle stays high. This is a 1 cpu
Linux (Intel(R) Xeon(TM) CPU 2.00GHz) machine. My gut feeling is that
the application (which they claim is slow) has a cpu bottleneck on the
web server.
Thanks in advance for any advice. (Sorry if the statistics are hard to
read)
