[squid-users] Squid - performance

Hi

I am running squid 2-5-10 stable on Redhat 9 as transparent proxy. Box
is having 2 GB memory.
As per my squid config
Cache_mem 256 mb
maximum_object_size_in_memory 200 KB
maximum_object_size 1024 KB
cache_replacement_policy heap GDSF
memory_replacement_policy heap GDSF
half_closed_clients off

I am using 2 Scsi hard disk of 36 GB for cache. I have assigned only 15
GB ( less than 50 % of total disk ) for cache in each disk .
So total cache is 30 GB.

cache_dir diskd /cache1/squid 15360 16 256 Q1=64 Q2=72
cache_dir diskd /cache2/squid 15360 16 256 Q1=64 Q2=72

I want to know if squid uses full 30 GB for cache then what will happen?
Shouldn't squid start deleting those cached objects which are not in
use?
Which parameter define that?

What parameters do I need to check to get best performance and caching.
My squid is currently handling 80 req/sec and during peak hours nearly
1500 users uses caching server.
I can save maximum 15 % to 18 % bandwidth. Is it possible to save more
bandwidth with better performance??

Thanks - Lk
