Hi,
I've been doing some testing using TTCP (from
http://www.pcausa.com/Utilities/pcattcp.htm) between two identical
servers. Both servers are running Windows 2003, and have GigE
interfaces.
The problem that I'm having is that I am getting very inconsistent
results when running TTCP, even with the same parameters, and with the
same sender and receiver. For example, doing a 2048 packet test (the
default) from server1 to server2, I have seen results from 7 Mbytes/sec
to 114 Mbytes/sec.
I have the feeling that this may be because I'm not waiting long enough
between tests, but I'm not able to confirm this with my testing, so I
was wondering if anyone here has experience with TTCP, and might be able
to tell what the problem is?
I'd also be interested in any other network performance tool that might
possibly do a better job?
Thanks in advance,
Jim
