i agree with aloycasmir,,,
a system,by which we can set the maximum cpu/bandwidth load after which, the website gets suspended automatically would be very useful....
Currently we have to manually check for high resource intensive websites when our server is under high load.
this is not limited to rapidleech etc only, Once , my client's website (which was joomla based) was cousing high server load, and i had to find it and manually suspend it, which took almost 30 minutes, until than, server was very slow.
so, automatic suspension would be great.
