[SR-Users] siptrace retransmission's

[Daniel-Constantin Mierla]

Hello,

I expect that the log message from sip trace means that a retransmission
was detected and it is not going to be sent to sipcature server.

Printing the log messages for memory operations (malloc/free) is going
to be very costly in terms of performaces, be sure that parameters
memlog/memdbg are lower than debug.

Also, depending of the config various tunings may be required for
increasing the perormances, such as value of children parameter.

Cheers,
Daniel
