If you want to be sure and have no xrun > whatsoever a -rt kernel is definetly the better choice imho (don't have > data to back that up though) I do have some data to back this up, I ran about 100 million samples with 2.6.14 and the biggest latency I saw was ~0.6 ms. For the buffer sizes he wants to use 2.6.14 will work fine. Of course you won't be able to sustain quite as high a DSP load but given the problems people are having with the -rt kernel on x64 it's worth investigating. Lee
