Re: [squid-users] Surfing hangs after period of time

I am worried about the Request memory hit ratios 0.0% part. This means that
my memory cache is unaffective, right? Where can I tune this?

Cache information for squid:
        Request Hit Ratios: 5min: 32.8%, 60min: 32.8%
        Byte Hit Ratios: 5min: 25.0%, 60min: 25.0%
        Request Memory Hit Ratios: 5min: 0.0%, 60min: 0.0%
        Request Disk Hit Ratios: 5min: 50.8%, 60min: 50.8%
        Storage Swap size: 1401944 KB
        Storage Mem size: 1144 KB
        Mean Object Size: 16.21 KB
        Requests given to unlinkd: 0
