thanks for the advice, i just increased cache size to 300 GB (i have 1 Terra raided hdd so i dont mind the size) as for object size i've set it to 15 MB. though one question, i've read that there's a certain option that keeps cached objects in memory for quick retrieval.. i've got 6 GB of ram, so i dont mind doing so.. any advice? would it do good or .. ? PS: i've started the delay pools yesterday i'll b testing it today to see if it works well.. once again thanks for the advice ---------------------------------------- > Date: Sun, 10 May 2009 23:20:31 +0100 > From: gavin.mccullagh@xxxxxx > To: squid-users@xxxxxxxxxxxxxxx > Subject: Re: speeding up browsing? any advice?! > > Hi, > > On Sun, 10 May 2009, Roland Roland wrote: > >> users on my network have been complaining of slow browsing sessions for a >> while now.. >> i'm trying to figure out ways to speed sessions up without necessarily >> upgrading my current bandwidth plan... > > Squid may help with this.
