Do I need to tune server for hotlinking?
 

I have one new server which i use for hotlinking of movies.
I Didnt have any problem with server I used for hotlinking before, but this one has really lot of exim processes, which cause high swap load, high memory use and high server load.
Is there a way how to decrease number of exim processes?

exim forks when it sends email so I assume you have a lot of emails in the queue.
On a side note using cpanel for a movie server is overkill.

if you have a seperate server for hotlinking media, i would just run web and ftp and ssh if you need it.

and run light httpd instead of apache.

since you dont need php or anything, will make it a lot faster

can i just cut off exim processes?. i dont need email on that server.

you can disable it from WHM under services.

I suggest you to ask your tech rep if there is something strange. Lots of exim processes in a server you don't use for mail looks like somebody is using your server to spam the world...
