BTW, I confirmed this regression. With vanilla 2.76.21-rc5 I get back my 5.4 secs with the test sample and two threads. Furtmermore for me vanilla actually feels nicer on my dual core, even with load - just subjectively that's why I ditched rsdl... Cheers, -- (°= =°) //\ Prakash Punnoor /\\ V_/ \_V
