The web filtering are using the other cores. The CPU usage was really reduced but without SMP I do not have any problem at all, I known no pain no gain but ... My advice, more than CPU buy RAM to support thousand of users you will never have enough RAM ! (64 Go if you can) and really fast disks - dedicated to cache - Also there are some little things that you can do to help you to improve your capacity, a squid restart each day, tuning the network, tuning the system, etc The bandwidth is a point, but the requests by second is THE point 20 users can get some 4K videos on youtube your bandwidth is consumed but your load average still close to 0.0 20 users with a spyware (or something similar) can push hundreds of requests by seconds, in this case your bandwidth can still stable - with the cache - but your load average increases It depends Fred _______________________________________________ squid-users mailing list squid-users@xxxxxxxxxxxxxxxxxxxxx http://lists.squid-cache.org/listinfo/squid-users
