Hi guys,

BTW: How did you measure this on Windows? And on Linux? What kernel
and jack versions? PureDyne is far from an up-to-date distro, as far
as I know.

50ms is a hell of a big latency for playing live, or recording with
monitoring and other kind of user cases.
But it all depends of what you want to do... :-)

I get 4ms here (ThinkPad laptop / intel i7 / ArchLinux), but higher
the latency less changes of xruns. So if I don't really need this
short latency I can set a little higher to ensure no xruns.

The word is that kernel 2.6.39 will have most of the rt patch
features, so things seems to improve very fast.
