Re: constant high CPU (>75%) w/ Squid25-STABLE10? thought it was cache-digests, but no ...

hi mark,

thx for the reply =)

hi all,

i've squid 25 stable 10 on osx 10.4.2.

it's 'front-ending' a privoxy + tor setup, with privoxy set as a cache peer
w/:

    cache_peer 127.0.0.1 parent 8118 7 no-query default

everything seems to work as hoped/expected.

but, i notice my CPU util for squid is CONSTANTLY high, typically 75-95%,
e.g.:

    24695 squid       82.1%  1:05.52   1    15    35  3.14M  4.90M  4.29M
    40.4M


 Perhaps , squid is in swap handling too much.
 Total process size seems bigger then the part in memory.

 Using os tools and commands , check whether squid is swapping.

well, that's a point ... i'll check when back in front of the box.

in the interim, i have found (stumbled across?) the (an?) apparent culprit ...

changing, in squid.conf,

   cache_peer 127.0.0.1 parent 8118 7 default

to

   cache_peer 127.0.0.1 parent 8118 7 no-netdb-exchange default

results in my squid-related CPU util staying, now, at < 1%, except, of course, when accessing a site/page ...

now, as to what i've lost/broken by disabling the 'netdb-exchange' i simply do not yet know/understand (rtfm'ing ...)


cheers,

richard
