Re: [squid-users] squid Process Size

hi
yes ive been following joe 's golden rules
so for abt 12 Gb of cache dir i hv given 100 MB cache_mem which is abt
umm 20 MB short of 10*12 = 120 MB
i was afraid that giving 120 MB from my 512 MB ram wud just in case
lead to swapping
right now the cache_dir is abt 26 %full so quite a long way to go
squid is already abt 180 MB
