How to limit a site's CPU on a web hosting server
some sites use little resource but some sites such as chatroom and forums need a lot resource.
question is how can I limit the heave cost site cpu and ram connections and bandwidth so that the light sites should work ok and whole server can run smothly.
I try lots of ways including set the site to isolated state and set the cpu limitd and limited the connections to 100,but seem not a good way.
sometimes will appear too many users to a 100 connections limit site even though I am quite sure that no people is visiting the site,but the page always show too many users untill i stop and restart the site.
and to the site that I limit its cpu,i can still find that the cpu it cost still higer than the max number i set.
I am a master of lots of web hosting servers,I need help of you,thx very much!
