Litespeed Tuning

Hi there
There is no documentation I can find that explains the Litespeed tuning options at all.

I have a few questions.

Is the litespeed tuining options set affect per website or the whole server?

The 2 settings I care about is Max Connections and Cache Size in memory.
Max Connections is default to 10000 and Cache size in memory is default to 20M.

In other words If Website has 10000 connections will website not work? or will also be allowed 10000 conenctions etc?

I dont know what settings to put there unless I know if the settings are per server or per website.
