Hi guys, I am using a couple of squid instances per server (Squid 3.1.0, RHEL 5.5, lots of RAM) and was wondering which would be the better configuration? Better in that case means more performance. Either 1) - 4 separate squid instances, each with its own completely independent cache? (no cache hierarchy or something like that) or 2) - a configuration similar to [1] with frontend and backend instances? Does anybody have experiences with either of these two configurations? We are currently using configuration #1 with 20 RPS/per instance and load values of up to 8. It is not much, but we are authenticating with Kerberos/NTLM/LDAP and even content filtering by ICAP. Load is pretty high, but since we are using 16 CPUs per server, it is ok until up to 16. CPU usage stays pretty low (<20%), and disk IO is not an issue (high IO idle values, very low IO wait values) too, I am wondering why the load is that high. What do you think, could configuration #2 improve performance (testing it would be best, but it is not that easy with a live system)? regards Peter [1] http://wiki.squid-cache.org/ConfigExamples/MultiCpuSystem
