Slow Transfer Speeds

I was send files to one of my storage servers and noticed I was only getting about 20MB per second transfer over my network.

All my other servers average about 110MB per second transfer over the network.

So, I went to the physical box and noticed that the CPU usage is almost 75% on a drive to drive (local) transfer of a file. (Test file was 1.2GB .mvk )

The speed did improve during the local transfer ( 85MB per second).

I then pulled the same file from the 1st server to this system and got about 60MB per second. CPU load was 50%.

Specs: Server 2008 R2 x64 , 4GB RAM, Celeron 430 @ 1.8ghz.

I am just guess that cpu is way under powered for this server. Any thoughts?

Software Raid5?

Xfering files shouldn't really use much CPU unless its running software raid.

NIC card if its software based can use CPU also, but not that much.
 
JBOB disks - WB 640GB AAKS drives for the first test.

The local transfer test was from that drive to software raid 1 drives.

The nic in that system is a PCI Intel 1000 GT with jumbo frames

Is that the single core 115 Celeron at 1.6GHz? I have the 530, 2.4GHz dual core and it idles lower than the single core (in terms of wattage). The 1.6 can't clock down.
