 Utilizing all cores, and encoding at ~4-12 times the speed doesn't make
 sense?
 What strange world you live in, where they want to keep encoding as slow
 as possible?

 I for one transcoded some DTS-HD MA movie streams to FLAC (level 12)
 roughly halving the space it took. And would have been really happy if it
 took a ~fourth of the time on my quad core cpu.
