Hi,
Preliminary results of the load test show red5 running out of memory (errors
can be seen in URL below) when it publishes several live streams.
The current load test sources version can be found here:
http://www.korandu.com/red5loadtests/red5loadtests.html
I will continue to try and improve and refactor the load test code.
Memory runs out before initiating play from the flash end. It seems
FLVReader is the one that seems to causes the out of memory errors.
I am using a 1.8GHz celeron, 756MB laptop. The more streams I initialize the
more in all honesty I hear my machine throttle (same like when you really
push your car engine hard); you can actually even "hear" the load test :-)
Tabulated results:
Number of live streams Out of Memory
- - - - - - - - - - - - - - - - - - - - - - - - - - - - -
10 No
20 No
30 No
40 No
50 No
60 No
70 No
80 No
90 No
100 No
110 No
120 No
130 Yes
200 Yes
Next up would be testing how red5 is able to handle subscription to several
live streams or even several subscriptions to a single live stream (ie how
many clients it can comfortably support).
The results are quite encouraging though because 120 simultaneous live
streams (though simultaneous subscription is not yet tested) is not bad
IMHO?
Who might have a more powerful machine available to do load tests?

Hi Chris,
I'm trying out the tests right now. I'll let you know how it goes.
Hello Thijs, how may I help?
