[Red5devs] Question Regarding Load Testing RTMP

[Daniel Rossi]

The red5bench is still on my server though im looking at the  
possibilities of some tools branch in google code maybe to add stuff  
there ??? There is even a flvrecorder thanks to other members help on  
this list i could contribute :D

The issue u will have with both the flex and java load tester is it  
needs to run from a server with a huge pipe or else u will get client  
side bottlenecks. The good thing with the jmeter profiler is u can  
setup remote control tests.
