[netperf-talk] netperf in windows environment

[anil mishra]

    Rick,
   
  Thanks for the reply.
   
  I am using Netperf 2.4 + downloaded from the trunk.
  I am not sure what is IIRC in your reply. I tried to use the -c option to get the CPU utilization while running my test, it gives me following :
   
  TCP STREAM TEST from 0.0.0.0 (0.0.0.0) port 0 AF_INET to 10.14.52.155 (10.14.52.155) port 0 AF_INET
Recv   Send    Send                          Utilization       Service Demand
Socket Socket  Message  Elapsed              Send     Recv     Send    Recv

  I am not sure if CPU Utilization (92.8 for local and -1.00 for remote ) values are correct.
   
  What is service demand metric printed in the result. 
   
  Can we also get the # of interrupts/sec metric from the Netperf?
   
   
  Yes, good point, I need to convert the script to .bat. Can I use them as it is in the Cygwin environment?
   
  Yes, you have done your math correctly.
   
  I got the following for the # trans/sec.
  
TCP REQUEST/RESPONSE TEST from 0.0.0.0 (0.0.0.0) port 0 AF_INET to 192.168.1.100
 (192.168.1.100) port 0 AF_INET

8192   8192
   
   
   
  I am trying to run the netserver on the Dell Poweredge 2900 system and it gives me following error messages:
   
  C:\netperf>netserver
netserver: fopen of debug file as new stdout failed!: The system cannot find the
 path specifie
   
  Am I missing something very obvious?
   
  Thanks much in advance for your help and for such a nice benchmarking tool.

Which version of netperf are you using? I would suggest at least 2.3 if 
not 2.4 from top of trunk in the subversion repository:

http://www.netperf.org/svn/netperf2/trunk

Netperf doesn't use configure under Windows. The README.windows file 
should describe how netperf is compiled under windows. IIRC that will 
include the Windows-specific CPU utilization measurement code you can 
access via -c/-C just like the rest of the platforms.

The set of "all available scripts" for netperf under Windows is the 
empty set as none of them have been ported to bat files. So, the first 
thing you would need to do is port them over to bat files.

If I've done my math correctly, that suggests you are seeing ~17K 
Transactions/second yes? Or is that one-way latency you are reporting?
