[squid-users] Newbie question: squid performance

Hi,

I am using SQUID-2.5.5 on RH Linux 8 with cache_mem of 50MB and cache_dir
size of 15GB. The cache is about 20% filled and I use GDSF replacement policy.

I am getting byte hit ratio of about 25% on my cache. I thought I would
get 50-60% on this ratio. My bottleneck is the bandwidth to Internet. So I
am really worried about the low hit ratios.

Is there any way I can improve my hit ratios?

TIA,
