I'm sorry
I reported this message here because I did not think it's related with
my JIRA reports.
They are about two segmentation faults, while this message is about load
testing not going very well, although it comes out during the same load
tests :-)

I'm starting to think that most people are using the sofia SIP stack in
fs to get rate of 100cps while the other interfaces such as event socket
and mod_xml_rpc are not well "engineered" yet. I'm going deeper into
this and I hope my results will be of help for the community.
At the moment I'm trying to understand the cause of TCP retransmissions
I see in the snoop, it seems that fs lags a little bit in sending the
TCP Ack back to the load runner, even with the machine doing nothing and
a really tiny amount of load.

BRs,
Claudio
