Re: [squid-users] Howto Clear Cache Periodicaly

Hi,
I did some testing on the cache, with the config
below. So I'm expecting when it reached 89% of cache
usage, which is about 2581000kb , the old data will be
replaced. How can I see that happening?, because at
the moment the cache used size is still increasing.
and I also experienced slowness during surfing.

Appreciate member's input on this matter. TQ.
