I have two machines hooked directy together through cat 5 both gigabit nics. I am trying some scp transfer and can only get 28MB/s. what is 224 Mb/s. That is only 22%. I tryied to adjust my sysctrl file from a few different sites. Did not change the number at all. Any ideas what would be slowing this to 28 MB/s.

I know that i am suppose to test this from the ram and not hard disk but the hard disk still rights faster then 28M/s

hdparm -t /dev/sda

/dev/sda:
 Timing buffered disk reads:  144 MB in  3.03 seconds =  47.58 MB/sec

Any help would be great, thanks!
