    Finally got this machine up 5.4-STABLE
    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
