support
i have ram 32 Giga .
i have 4 hardsiks as follow:
hardisk#1==>opertaing system 170 giga ssd hardsik with name sda

hardsik#2 , hardsik#3 , hardsik#4 , ===>had been as raid 0 with name sdb

ive woring wccp2 with cisco router with tproxy without ptoblems .

but the main problem is that there is slow in browsing and squid guard
sometimes bypass the filtering !!!
