Re: CakePHP high CPU utilization

Hello again,

so, I've installed an nginx and php5-cgi, and configured cake access
through this scenario - before nginx there is an apache proxy.

I _can't_ increment the CPU usage with ab!!! I tried to increment the
number of request:

ab -n 10000 -c 100 http://mysite/foo

but the max CPU usage was like these:

20.26.53 CPU %user %nice %system %iowait %steal %idle
20.26.54 all 0,35 0,00 0,35 0,12 0,00 99,19
20.26.54 0 0,00 0,00 0,00 0,00 0,00 100,00
20.26.54 1 2,00 0,00 0,00 0,00 0,00 98,00
20.26.54 2 0,00 0,00 0,88 0,00 0,00 99,12
20.26.54 3 0,00 0,00 0,00 0,00 0,00 100,00
20.26.54 4 0,00 0,00 0,00 0,00 0,00 100,00
20.26.54 5 0,00 0,00 0,93 0,00 0,00 99,07
20.26.54 6 0,00 0,00 0,98 0,00 0,00 99,02
20.26.54 7 0,00 0,00 0,00 0,00 0,00 100,00

In first point of this, I think this is extremely high performance increasing...

But I don't understand, why it so bad the results when I measured it
through apache2 and mod-php, cause another frameworks gives same
results like this above - a few percent on few cores.

Any ideas?

thanks:

a.
