Subject Re: Using JMeter over subnets 192.x.x.x or 10.x.x.x
Date Wed, 21 Feb 2007 11:52:09 GMT
Hi All,

Thanks for your responses.

I hope it means with Jmeter I just need to have the remote clients and the 
controlling client in the same subnet, irrespective of the server location 
and the subnet IP. Please correct me if I am wrong.

What  i have been able to detect is anomalies in TPS calculation , which 
falls drastically with a client from another subnet is started. Your 
explaination is a fitting one , as it might not be able to contact the 
controlling client.

But then the value stabilizes at times .. any reason why so ? Please note 
that the tool is being evaluated with a broader picture in view , as it 
will be used to performance test various data centers or mirrored servers 
or even bandwidth requirements.

Just wanted to be sure with them , before i made the big leap.

Thanks in advance for any help on this.

best regards,

Well put.
