I'm using httperf test squid, the latencey goes up plateaus at 3000ms (3
seconds) @ about 500 connections/second then goes exponential.
Seems kind of strange.
Config is below:
#http_port 8090 vhost
http_port 8090
#enables or disable ICP
icp_port 0
#icp_port 3130
#htcp_port 4827
#
#
#
#for syntax see http://www.visolve.com/squid/squid30/neighboursel.php
