[squid-users] "Efficiency" of around 10%, is that normal

Hello,
 
I was used to getting efficiencies of around 50%. My current setup does
not get past 10% as reported by Calamaris. There are around 40 people
behind the proxy. After Googling around I added the following lines to
squid.conf:
 
cache_mem 256 MB
maximum_object_size 32 MB
maximum_object_size_in_memory 128 KB

System has 512Mb of memory and very little other tasks. Is there
anything else I can do to improve efficieny?
 
Thank you,
Bas
