Galit, All informations depends from your squid configurations, example: if you setup the cache memory for 2gb and yours users are going have on max this for using to cache. You have to be carefully with the configuration related with cache memory and cache disk. Could you inform the hardware wich use from this squid? Are you using something system for monitor this squid?
