Hi ,

Is anyone aware of how many SIP MESSAGE per sec asterisk can handle , is there a benchmark has this been load tested and results available some where , if there is can you some one share it please .

The reason is we ran 16 per sec and we see the ast_msg_queue is backing up with lot of messages
<GH>This may depend on your test setup. Are you sending between a fixed pair of URI:s, or multiple?
Have you considered this rule from RFC 3428? "

   A UAC MUST NOT initiate a new out-of-dialog MESSAGE transaction to a
   given URI if there is a previous out-of-dialog transaction pending
   for the same URI."

So, if you are sending between one pair of URI:s, the sender needs to wait for 
a final response before sending next MESSAGE. With usual network delays that 
can mean a maximum of about 5 MESSAGE per second or so.

With multiple URIs on both sides, the figure should be higher.

Regards
Gunnar


thanks,
Bala
