But maybe can use more threads ? (i have 6 cores all with ht , but uspp 
uses only one thread....) maybe some ssse3 or sse4 operations can speed 
that snow encoder? Maybe snow  needs more internal buffering? even 20% 
is good  (with uspp=6:8 i have 0,68 fps encoding .....) 20% can be a few 
hours difference, but don't know if without that option it will do the 
same good job
