Re: [squid-users] requests per second

Hi,

We are using Squid as forward-proxy for about 10-20k clients with
about 1200RPS.

In our setup, we are using 4 physical servers (HP ProLiant DL380 G6/G7
with 16CPU, 32GB RAM) with RHEL5.8 64Bit as OS with a dedicated
hardware loadbalancer. At the moment, the average server load is
approx 0.6.

We are currently using:
Squid Cache: Version 3.1.16
configure options: '--enable-ssl' '--enable-icap-client'
'--sysconfdir=/etc/squid' '--enable-async-io' '--enable-snmp'
'--enable-poll' '--with-maxfd=32768' '--enable-storeio=aufs'
'--enable-removal-policies=heap,lru' '--enable-epoll'
'--disable-ident-lookups' '--enable-truncate'
'--with-logdir=/var/log/squid' '--with-pidfile=/var/run/squid.pid'
'--with-default-user=squid' '--prefix=/opt/squid' '--enable-auth=basic
digest ntlm negotiate'
'-enable-negotiate-auth-helpers=squid_kerb_auth'
'--with-aufs-threads=32' '--enable-linux-netfilter'
'--enable-external-acl-helpers' --with-squid=/home/squid/squid-3.1.16
--enable-ltdl-convenience

IMHO, it is really important which features you are planning to use.
For example, we are using authentication (kerberos, ntlm, ldap) and
ICAP content adaption. Without that, our RPS-rate would be much
higher. Because of a lacking SMP-support in 3.1, we are using 4
instances per server. At the beginning, the setup used to be much
simpler! ;-)

hth,
Peter
