Hi ,
I am facing some performance issues in squid .
i.e. I have Debian etch with squid,squidguard,shorewall.
Internet is working in normal speed if clients are approx 50 .
If clients are approx 70 -100 it is getting very slow.
I googled for tuning and done the following things,
redirect_children 10
cache_dir ufs /var/spool/squid 1000 16 256
cache_mem 48 MB
pipeline_prefetch on
fqdncache_size 2048
maximum_object_size 8192 KB
Can you please suggest me how can i improve much ?
* Try AUFS cache_dir type. Works well, even in Etch.
* You have heaps of RAM, bump up the cache_mem if you can. That will
leave more objects in RAM-cache for faster fetches.
* only 1GB of cache is currently allocated. test increasing that a bit
as well.
* turn off pipeline_prefetch.
* turn on collaped_forwarding.
* do what you can to eliminate the redirector.
that may mean fast ACLs and url_rewrite_access
* use the latest squid.
If things continue, check the cachemgr stats and see if there is any
indication of whats slowing things down.
