Re: [squid-users] browsing stop when delaypools reach limit

i have test on squid 2.6stable3 configure with --enable-select instead
of --enable-poll and there's a bit improvement on delay pools
perfomance but not make me satisfied yet :(

./configure option on my openbsd 3.9
====================================
Squid Cache: Version 2.6.STABLE3-20060819
configure options: '-enable-http-violations' '--sysconfdir=/etc/squid'
'--enable-removal-policies=lru,heap' '--enable-storeio=ufs,aufs'
'--enable-delay-pools' '--disable-cache-digests' '--disable-wccp'
'--disable-wccpv2' '--enable-underscores' '--enable-pf-transparent'
'--disable-follow-x-forwarded-for' '--enable-large-cache-files'
'--enable-default-languages=English' '--enable-err-languages=English'
'--disable-ssl' '--disable-ident-lookups' '--disable-hostname-checks'
'--disable-htcp' '--enable-icp'

additional option that effect to delay pools
============================================
--enable-kqueue = bad
--enable-poll = a bit better than kqueue
--enable-select = a bit better than poll
--enable-epoll = not support

client side test environtment
=============================
platinum users with delay pools 6000/6000
download manager, download 1 file with pararel 8 http sessions
browsing with firefox while downloading

problem
=======
delay pools sometimes cant make fair queueing that let download eat all
allocated bandwith so browsing is not possible or got very long time
wait before html page requested appear because too small free bandwith
available.

what else should i do to make delay pools working smoother?

regards,
Pudjo
