ftp to localhost
starts on 10.2mb/sec, goes stable for a short while, then stops for a few seconds (4-5), then continues in about 5-6 until the transfer is complete.
all my stuff are on seperate irq's.
when I copy, "system" load skyrockets, 60-85%.
lftp and glftpd is the processes using resources. I could try smb aswell, but I'm guessing I'll find that eating my system resources aswell.
