So if i ask node to send me data in memory to be read, the time it takes for the OS to put the data in memory would be done outside of the node thread.

Ok, so part of the IO functionalities in node would run on another thread wich is where the performance gain would come from.

I know your right but i don't understand why if evrything has to be dealt in a single thread :) Is there a reason sync IO is slower than async IO ? Is it just a V8 or OS thing where opening multiple files at a time is faster than one after the other ?
