OK, so you do less than 200 lu/s even in that favorable case. Our DC is
hit by some four figure number of clients I suppose. I've asked my
colleague to check the lookup rate on our test web server and he also
gets around 30 lu/s with caching disabled, just like I did via Cygwin.
So the network speed isn't the limiting factor.

Sounds interesting.

Gets even better… :-)

Bring it on. I'd need 32bit DLL since I have to keep the 64bit Cygwin
running on my machine.
