RE: [reSIProcate] reSIProcate speed is much slower now
Great. The problem seems to have been fixed. Now the testSpeed program
is generating 395 calls per second (even more than the results obtained
from reSIP 0.9).
Thanks for taking care of this...

Subject: RE: [reSIProcate] reSIProcate speed is much slower now
I did some investigation into this issue and found that a relatively
recent addition to the WinCompat code is causing the slowness. If you
build with USE_IPV6, then WinCompat uses the
determineSourceInterfaceWithIPV6 function, as opposed to the
determineSourceInterfaceWithoutIPV6 function. The
WithIPV6 version can end up taking 100-200ms to return - thus slowing
down the entire test.
This function needs to be fixed - but in the meantime, I've modified the
code so that even if the USE_IPV6 flag is turned on, if the IP Address
is a
V4 address then it will use the "WithoutIPV6" version instead. This
means that the performance is restored for IPV4 addresses, and only IPV6
addresses will be slow.
Thanks,
Scott

I set the logging to "Error". Nothing was printed by the program while
the test ran.
Log::initialize(Log::Cout, Log::Err, argv[0]);
I also built the stack and test program in Win32-Release mode. Did not
change the reSIP settings. I see that it is set to - Full Optimization
(Ox) and Favor Fast Code (/Oy)

Did you build with optimization turned on? Also, is any logging enabled?
What type of logging (i.e. file-based)?
