LINK STATE SPEED DUPLEX

A bit speed testing with dd:
[EMAIL PROTECTED]:/etc# dd if=/dev/zero of=/storagepool/users/test.dump bs=128k
2035941376 bytes (2.0 GB) copied, 23.6579 seconds, 86.1 MB/s
The network rate is about 35-45 MB/s when copying large files from Windows XP
over CIFS to the ZFS share. At the same time "zpool iostat 5" shows write speed
which is jumping in the following manner (there's actual sequent numbers for
write speed) 50.9M, 43.0M, 7.88M, 50.9M, 50.9M, 18.6M, 32.3M, 50.9M
Monitoring "iostat -xnz 1" shows the following trend (while copying large files
from windows):
three seconds of writing

then three seconds without any writing. Then again three seconds of writing
following with three seconds without writing.
My machine is based on GIGABYTE GA-P35-DS3P motherboard with Intel Code 2 Duo
processor, 2GB fast 800Mhz DDR2 ram in dual-channel configuration and three
Seagate 7200.11 750GB disks connected to the motherboard SATA controler running
in AHCI mode. The motherboard uses Realtek 8111B network chipset to provide the
gigabit ethernet.
Does that info help anything?
