Windows file copy is tremendously slow
by irrani dam on Nov 3, 2009 at 1:31:30 am

Hi,

I'm copying a large database file (23GB) from one mounted iSCSI
volume
to another. It's taking over an hour to copy. Network utilization and
CPU on the host and iSCSI server are fine.
The MegaRaid perfomance monitor on the iSCSI box(storage
concentrator)
shows the disk activity in waves:
10MB/sec at 200 "I/O"/sec
then
4000KB/sec at 60 "I/O"/sec
Devices are connected via a single gigabit ethernet connection each,
via a Cisco 3750 switch. They are the only active hosts on a storage
VLAN.
Any suggestion or recommendation to speed up the copy function.

IrrANI
