Best tool for network throughput testing...?

JDxtra

I’m looking for a tool to test network throughput between two PC’s. This is to test real world speed achieved across a LAN or WAN.

I’ve tried a number of tools – but they all give varying results.

Is there any definitive tool out there that is well regarded?

Thanks.

DID you look at performance monitor ?

I've not used that before for measuring throughput between two PC’s - not sure if would be entirely practical to use it for this.

I've used some DOS based apps before. You run one as a 'server' and another as a client and get the client to send a chunk of data to server (10, 100mb or whatever). It then returns back telling you how long it took and what the average speed was.

Only problem is that this is just an app written by some student and the results have been questioned.

So, I'm really looking for something well regarded within the industry.

I see
I have an app in work for what ur looking for
It was sent to me from Commvault - One of the biggest backup software packages out there.
I'll have a look for it tomorrow
