I’m confused about this tool.
It says:
iperf -c 10.0.0.250 -t 600

it’s gigabit network on gigabit switch, all cards are Gigabit. The only difference is I’m trying to get 1Gbit/s via bridged and bonded interface in server.

Hi,

I have saved iperf exe file in the D drive and run iperf as a server in the location where the Iperf executable resides. But i always have this error when setting it as server, ‘OpenSCManager failed – Access is denied. (0×5)’. Would appreciate if you can help me as I am new in using iperf. I have no problem when using it as client. Thanks!

Comment on Implementing RAID1 on Windows Server 2003 by mickeway

mickeway — Sun, 15 Jan 2012 13:28:39 +0000

I have two new similar HDD. I have installed Windows Server 2003 on one HDD and I wonder whether I should format and install Windows Server 2003 on the other one too before I do the RAID1? Or should I only format it or should I neither format nor install Windows Server 2003 on it?

Thanks for a very coherent and concise explanation otherwise,

mickeway

Comment on Iperf on Windows by CC Hsiang

I tried to do some TCP connection scale/stress test using -P parameter. When I do “-P 10″, the tool works ok, but if I do “-P” with a higher number, e.g. 200, the tool crashed with stackdump.
Is this a known bug? Is there a limitation on how many TCP connections can be tested at the same time?
Thanks in advance.
