Hi Alon,

Hello all,
There is an abnormality in the openvpn sources I want to resolve.
In windows there is own implementation of gettimeofday().
In the past there was no gettimeofday(), so we used performance counters,
then James optimize it to reduce CPU consumption.
Unlike in the past, mingw does provide this function these days.
The question is if it is good enough.
There is also a note:
/* on WIN32, gettimeofday is faster than time(NULL) */
I am not sure about any of these, can you please try to run the
benchmark and report back the results?
It must be compiled using mingw, either at cygwin or at linux.
First:
$ i686-pc-mingw32-gcc -o timebench.exe timebench.c
In a virtual WinXP SP3 env on my 2.50 GHz Intel T9300:
c:\users\janjust>timebench.exe
time(): 18
gettimeofday(): 47
openvpn_gettimeofday(): 16
share and enjoy,
JJK
