If you limit the download speed, then proftpd will not use "sendfile" systemcall to reduce the load, in fact, that will trash your system very hard.But since your box is fast, it should not be a issue.
Another reason is the files users are downloading are not continuous, this will cause harddistk move the arm ,then reduce the performance.Does your disk trash when several users are downloading?
Use "top" to see which process is eating up the CPU? |
