RE: [squid-users] speeding up browsing? any advice?!

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
