In the "good" case you are getting a much higher interrupt rate but
with the data you provided I can't tell where from. You need to run
vmstat -i at regular intervals (e.g. every 10 seconds for a minute)
during the "good" and "bad" times, since it only provides counters and
an average rate over the uptime of the system.
Now I'm running 10-process lighttpd and the problem became no so big.
I collected interrupt stats and it shows no relation beetween
ionterrupts and slowdowns. Here is it:

Also I have similiar statistics on mutex profiling and it shows there's
no problem in mutexes. http://83.167.98.162/gprof/mtx-graph/mtxgifnew/
I have no idea what else to check.
With best regards,

I don't know what this graph is showing me :) When precisely is the
system behaving poorly?
