The problem is almost certainly RapidLeech and not your set up. So long
as you are transferring/zipping files that will consume large amounts of
CPU. Downloading large files can take significant amounts of time.

We don’t allow RapidLeech to be installed on our servers for this
reason, and for the potential legal issues associated with illegal file
transfers.

it means that rapidleech is the problem??? but i dont think but i have
one site in a dedicated server and its for leeching :

Xeon 3060 (4.8GHz, 2 cores)
1066MHz FSB 4MB L2cache
2GB Memory

and limit of transfer is fixed on 200MB but php-cgi still consume %90
of CPU …

Well when php compress something, it’s normal that it use all available
power for one process.

Check if you have there xcache or pecl-apc. Also, you can play with
cpulimit wrapper to php (depends how you running php-cgi) to limit php
cpu usage.

i fixed transfer limit to 100MB and actually problem has solved …
now CPU Usage is : %2 and Free memory : 1GB
exactly this problem was started when trasfers files limited to 200MB :frowning:
and Not compatible with 100Mbit Connections…

Thank you .
