RE: [squid-users] cache/mem ratio ok but swap grows

Henrik or others,

I really want to enlarge my storage from 28 gig to 50 gig but are unsure
whether the memory figures I'm getting at the moment will let me.

Can I go to 50 gig without locking up?

Top sorted by mem usage.

I'm running RedHat 7.3

Machine config, squid.conf and mrtg below.

Kind Regards

Stuart Clark (RHCE)

What does Squid say about it's memory usage?

What OS are you running on?
