[libmicrohttpd] Performance problem under Windows

[Martin Bisson]

Hi,

I'm using libmicrohttpd Windows build (the latest I found is 
libmicrohttpd-0.4.5-w32.zip) and I'm having some performance problems.

I wrote a simple Python script that does sequential (only one thread) 
HTTP POST requests in order to measure how fast a single client can make 
requests (sort of a measure of latency).  Using a slight modification of 
the simple server found at http://www.gnu.org/software/libmicrohttpd/ 
running on the same computer as the Python script, I get a little more 
than 1 second per request.  If I use the same script to send the request 
to an Linux Apache server on another computer on my LAN, I get around 12 
ms per request.

I find the "little more than 1 second per request" a little suspicious.  
I looked at the code in daemon.c and both the select() and the poll() 
calls use a 1 second timeout...  I was wondering if there might be a 
problem with that under Windows...?  Or is the 1 second per request an 
expected latency for libmicrohttpd with client & server on the same 
computer?

Has anyone had this problem under Windows or can anyone point me to 
solution path?

Thanks,

Mart
