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)?
