Dual 244 2GB RAM 5 x Seagate 400GB on HPT1820A
Initial tests using: nttcp -T -n100000 <machine> from two clients 1. WinXP P4 Intel gE 2. FreeBSD 5.3-RELEASE dual PIII 733 Intel gE ( 4x WD250 IDE on HPT374) To the test machine 78MB/s I could well be saturating the clients will get another machine hooked up and see if it does more. Using proftpd on the test box and ftp clients on the other two max was 54MB/s
dd if=/dev/da0 of=/dev/null bs=128k count=10000 10000+0 records in 10000+0 records out 1310720000 bytes transferred in 24.067986 secs (54459064 bytes/sec) time cat current.iso > /dev/null 0.007u 0.478s 0:00.48 97.9% 10+184k 0+0io 1pf+0w 528Mb/s ( memory speed )
On the old PIII I get: dd if=/dev/da0 of=/dev/null bs=128k count=10000 10000+0 records in 10000+0 records out 1310720000 bytes transferred in 39.415163 secs (33254207 bytes/sec) time cat current.iso > /dev/null 0.054u 1.585s 0:01.64 99.3% 10+180k 0+0io 0pf+0w 159Mb/s ( memory speed )
Comments: dd speed seems very low, netspeed seems good using nttcp considering its using the cheapo onboard BCM5705

I will be putting together a dual Opteron this weekend with the hope of testing network throughput. Spec will be: Dual 244, 2Gb RAM, 5x400Gb SATA RAID 5 on a Highpoint 1820a Broadcom 5705, Intel gE and a Intel dual port ( PCI 32 ) for comparison.
Will let you know the results.
