Re: [microblaze-uclinux] TCP transmit performance

[Jim Van Vorst <jvanvorst@xxxxxxxxx>]

Falk,

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.

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.

From your microblaze system, run "netperf -H <netserver host ip>"

That will blast max size tcp packets to netserver host ip (the ip address where you ran netserver) and give you a throughput number.

netperf has a bunch of other options for tcp, udp, zero copy, etc.  It's a generally useful utility.

Can you compile and run netperf to get Mbits/sec TCP tx throughput?
    

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. :)

CU, F@lk
