We have an ISP deployment in which we reach performance limits in Squid, so we try to tune anything possible to get more performance. I would like to know if there is a reason why this check has been implemented (e.g. possible side-effects, etc.) or that it can be removed safely. Upgrading to squid 3.x is unfortunately no option since COSS support is missing and Rockstore isn't ready for testing yet. -------- Original-Nachricht -------- > Datum: Mon, 31 Jan 2011 12:08:55 +0200 > Von: Eliezer <eliezer@xxxxxxxxxxxxxxxxxx> > An: squid-users@xxxxxxxxxxxxxxx > Betreff: Re: TCP send/receive buffer tuning > i dont know how high performance your system is but i think you can try > the new version 3.1.10 on your system and after you will get real > performance > issues you can try to recompile it with less strick option.. or .. just > compile one with limit and one without limit and change the binary if > you dont get results. > > as long as i know 64k is really more then many systems needs for a > buffer. > > > > On 31/01/2011 11:57, Jack Falworth wrote: > > > Hi squid-users, > > > > I have a question regarding the TCP send/receive buffer size Squid uses. > > For my high-performance setup I increased both buffer sizes on my Ubuntu > 10.04 system.
