Hi.

I was going to add some pipelining and to existing squid-based infrastructure, and I set up Polipo as recommended there: http://permalink.gmane.org/gmane.comp.web.polipo.user/1099

Then I set up polipo & squid like that: http://unquietwiki.blogspot.ru/2010/02/squid-polipo-to-make-high-speed.html
(polipo: allowedClients = "127.0.0.1", diskCacheRoot = "", dnsQueryIPv6 = no)

Testing with few users shown good performance, but once I put it into "production", polipo started draining all CPU resources, and serving requests very slowly (about 2-3 per second).

System it's been running on (and where squid-nt alone works very well, with about 15% average CPU load):
Windows 2003 Server, AMD Sempron 2500+, 512 MB of RAM.
There are about 30 users going through the proxy.

I'm using polipo-1.1.0-win32.zip from http://www.pps.univ-paris-diderot.fr/~jch/software/files/polipo/

Unfortunately, I've got no build tools at hand, so I can't profile or debug outright. But if someone provides me with binaries, I'll do it.
