Measure Performance over network

[panchpan]

Hello.
In Extranet, we have customer accessing the Production Server. I wish to measure the performance in quantitative figures.
The reason to do so is in future the physical location for prod server is going to be changed and i wish to have some figure to keep same performance speed.

Is it possible?
Thank you.

Shalom,

netstat -i 3

Set the measurement time in the script and do multiple collections of data for reach configuration.

Also: gpm frm glanceplus can help.

Hi,

In my experience, the best tool for measuring network performance is netperf, written by HP's own Rick Jones.

You can download a free copy of netperf and the documentation from:

http://www.netperf.org/netperf/NetperfPage.html

This tool can be used to simulate nearly any type of network traffic and give you exact measurements of throughput. It would be great to collect a baseline set of measurements of different network traffic (inbound UDP, inbound TCP, outbound UDP, outbound TCP, etc.) and then compare these against the same tests once the server is relocated.

If you happen to know what type of network traffic your applications use, I'm sure you could run a netperf test to simulate those types of network transactions/traffic. Those test results would be especially useful after the server is relocated. For example, if your application uses UDP in a request/response fashion then knowing the TCP Stream test results might not be that useful but having the UDP_RR test results would be critical.

The more you know about the networking behavior of your applications, the better you'll be able to customize the netperf tests to simulate them. Things like the size of the request packets can make a huge difference in performance - and again, the closer you get to your real application behavior the more useful the data will be.

I hope this helps,

Dave

I went through the briefs of netperf - But could not make out how to download/use it.

Can you please guide me in short tips?

Thank you.
