Hi, I am using 2.6.21-rc5 with rsdl 0.37 and think I still see a regression
with my Athlon X2. Namely using this ac3 encoder
(, which I parallelized in a simple way, with
my test sample I remember having encoding times of ~5.4sec with vanilla and
~5.8 sec with rsdl - once the whole test wave is in cache. Otherwise you can
easily I/O limit the encoder. ;-) You need to get sources from svn though.
The current 0.06 release doesn't have threads support.
