Im having the same exact problem. Does your CPU utilization jump up to 100% once your ram gets filled? Thats what mine does. Then, abysmal network performance.

I have 3 500gb WD SataII HD's in RAID 5.

In srodgers' case he has 2GB RAM in Dual-Channel mode. Notice how the syslog says only 896 will be used. Try physically removing anything above 1GB, and maybe even stepping down to 512 (if you can).

I still have Himalayan transfer throughput at gigabit - I'm using the Netgear GA311 throughput monitor on a client machine to indicate it's throughput. My two main RAID drives are 1250GB and 1000GB respectively - one HP/Adaptec 2610SA based, 6 x 250GB SATA RAID5, the other 3Ware 7500-8 based, 3 x 500GB ATA100 RAID5.

When transferring to the NAS I get a burst of throughput then a pause, repeat until complete. When I revert to 100Mbit, I get a nice, fairly smooth line.

I'd consider that to be normal if your controller is slower than the NIC.

I actually only have 512 in my system, in single channel. My speeds are very sporadic though.
