Hi all

Thanks for all the input.

Unfortunately we're struggling to hit the performance figures we expect. We
have tried deploying JMeter on a higher spec box, using multiple injectors
and we're going to see if running in console mode will help significantly.

If anyone has anything further to add it'd be much appreciated.

Thanks again

/Ross

Using multiple test machines to test load on the server machine can help 
you too to achieve higher throughput... (but I never did it with jmeter)

see: http://jakarta.apache.org/jmeter/usermanual/remote-test.html
