The petalinux distro includes the netperf client. You just enable it
in menuconfig under Network Application. Enable netperf and netperf
client. Rebuild and it ends up in /bin.<br>
<br>
You also need to run the server. Download the source to a *nix machine
(windows may work as well, but I haven't tried it). Extract the
sources, go into the source directory, type "./configure" and "make".
That should build netperf and netserver. You want to run netserver.<br>
<br>
From your microblaze system, run "netperf -H <netserver host ip>"<br>
<br>
That will blast max size tcp packets to netserver host ip (the ip
address where you ran netserver) and give you a throughput number.<br>
<br>
netperf has a bunch of other options for tcp, udp, zero copy, etc.
It's a generally useful utility.<br>

<pre wrap=""><!---->I had a short look at netperf.org but gave up in a flood of \
docs. Seems it's not a 5-minute job to measure with netperf, right? Or can you tell \
me what to do, maybe it's a simple line to type on command prompt? I need a very \
short HowTo. :)
