Yes, it is the win32 version, but its an old one (1998), not sure how
the config file will carry to a more recent version.
IOmeter Access specifications:
Transfer req. size = 64Kb & 8Kb
Percent of Access Specification = 100%
Type of Operation: 100% read; 100% write; 50% read
Percent Random/Sequential Distribution: 100% sequential
Queue Depth = 8
Reply Size: No Reply
Burst Length = 25 I/Os
Align I/Os on: 64Kb & 8Kb
Ramp up Time = 30sec
Run Time = 3 min
# of clients used: 1 to 9 clients (Linear Stepping)
Note that the problem is visible with only one client.
The clients are GbE as is the server, not sure if you will see a
difference on 100BT.
Thank you very much for looking at this, please let me know if there is
anything I can do to help.
Regards,
Greg
