EXS 24 Logic Sampler Users Group

Just wondering if any TDM users of Logic have tested if streaming  
string samples from a TDM EXS is any more or less CPU or disk I/O  
intensive than running the exact same thing in Native.
My brief tests over the last few days have the native version  
handling tasks better.
Come to think of it does anyone know if VM actually works on the TDM  
version? I mean it's there in in the prefs but does it actually work?
