Re: [squid-users] Squid Proxy sizes

Hi all,

Personally, I find determining cache servers/size is more of an art...

Is there any mathematical formula to estimate the number of caching server
and cache size required, based on the In-Out traffic (Mbps) and Req/s?

Eg. In traffic: 140 Mbps
         Out traffic: 100 Mbps
        Req/s: 1500

Thanks,
Wei Keong
