I´m releasing an experimental version wich support asynchronous rdp emulation. It´s not perfectly stable at the momnt, but under linux I notice a slight speedup (maybe between 10% and 20%, it´s not completely obvious to measure)

I´d like to know if it improves things under win32, on mono and multi processors.

You need to make sure "threaded" and "async" are both set to 1 in the config file.
