Can you please check the raw C perf tests (in perf subdirectory of the 
core library) to check whether the bad performance is caused by 0mq as 
such or by the C# binding?

Guys, this is the second report of 0mq being slow on Windows in two 
days. Haven't we messed something up? Does anybody of the core devs have 
two windows boxes to check how the current version performs?
