So your router is intercepting Squid's traffic and redirecting it back to Squid. That's not so good. In a big way.
And here is some of my squid.conf # Squid normally listens to port 3128 #http_port 3128 http_port 3128 transparent #Default: # cache_mem 8 MB cache_mem 512 MB #Default: # maximum_object_size 4096 KB maximum_object_size 25600 KB#Default: cache_dir ufs /usr/local/squid/var/cache 2500 16 256 # this one is a symlink to another disk
A symlink, or is the other disk mounted here. No matter, but you should probably be using aufs, which you will have to compile support for.
cache_dir ufs /usr/local/squid/var/cache2 2500 16 256
So how much memory does this box have? You've dedicated about a GB of RAM for Squid alone (512 cache_mem + (5GB of cache_dir * 0.1)).
all the other option is default value and I have some config for wccp
And apparently some url_rewriters (unless those are implied by using wccp...).
