Checking network throughput

[johnrr6]

What do you folks use to check network throughput???

Qcheck???

something else??

I'm getting ready to "upgrade" my 10/100 network to 10/100/1000.

Want to see what I'm getting now----then compare after the upgrade.....

And what do you guys consider "good" average achieved speeds for a normal home network at 10/100???

And following----what do you consider "good" average achieved speeds for a normal home network at gigabit speeds???

thanks for any help.

John

is there any tools to check network throughput?

People are often concerned about measuring the maximum data throughput rate of a communications link or network access. A typical method of performing a measurement is to transfer a 'large' file and measure the time taken to do so. The throughput is then calculated by dividing the file size by the time to get the throughput in megabits, kilobits, or bits per second.

There are several tools for this you can google out for that and find the best suited one as per your needs and requirements

Which tool would you recommend Saffi...or does it always depend on you needs?

[saffionline]

Well when it come to me i would rather go for iPref... which i use to use constantly to check on the status about my network performances...

I've a tool called showtraf-1.6.0 which shows in realtime what the useage is. Forgot where I downloaded it from but I think it was from someone here at ABX. On to your question, I've heard that even most larger networks only utilize around 10 percent of the available bandwidth so gigabit will be overkill. But heck its so cheap now, even my laptop has it so why not go for it. I'd like to upgrade myself but cant find a 2960 under 200

You may enjoy reading this thread where StarTraveller does some work in testing throughput. New wireless router - D-Link DGL-4300 owners chime in, please!

the 1Gb switch also connects to my 100Mb router for internet and to lead onto my WLAN. What i'm trying to check is that the traffic communicating between the Media Centre PC and the Network storage is running at 1Gb as it should?

iperf is what you want. Download version 1.7.0; 2.2.0 isn't really trusted by anyone yet.

Setup the server like this:
iperf -s -u -l 2500

Then run the client like so:
iperf -c x.x.x.x -u -b 800m -t 200 -l
(Replace x.x.x.x with the server's IP obviously.)

Keep in mind that realistic expectations for 1000Base-T is only about 400-500Mb/s.

This is pretty damn vague. Workgroup switches probably don't need to be on gig, but I sure as hell want my NOC equipment on it.

You will never see any engineer worth anything use this method, simply because it does not help with TCP tuning. iperf, and to a lesser extent netperf, are used first to properly test and tune the link before any file testing is done.
