How new is the version of LAME you're using?  If it's newer than 3.93.1,
a lot more 'quality' has been added to the higher-quality settings; so
aq=0 is a lot slower than it used to be.  Try aq=5 and listen carefully
to decide whether the resulting audio is acceptable for you.  If not, 
try aq=2 or aq=1.
