QueueChannel Perfomances

[Alexis Chaupin]

Hi,

I am new with Retlang.
I would like to use Retlang in order to queue actions and execute them on the first ThreadFiber available. (Looking for high perf : at least 1MillionMsg/sec)

For that I used a QueueChannel but my benchmark returns strange results :

#Results with the number of ThreadFiber subscribed to the QueueChannel :
1 ThreadFiber ~= 1sec
2 ThreadFibers ~=> 3sec
3 ThreadFibers ~=> 5sec
4 ThreadFibers ~=> 8sec
5 ThreadFibers ~=> 10sec

Code : http://pastebin.com/jf4iWXVS

I was expecting a decrease in the processing time of dequeuing.

Thanks for you help,
Alex

The receive method does nothing so most of the time is spent context switching and thrashing on locks. This will cause the total execution time to be dramatically slower. A queue channel will only be faster if the receive method actually takes a few cycles. Also, if you just want parallel execution, then the standard .NET thread pool works fine.
