2.4. if you

2.6 vs.
RT-patched 2.4, the latter is still better.
I'm not sure that is even true any more. No
recent data, but I tested
jackd
extensively in about the 2.6.7 to 2.6.11 time-frame,
and found those
vanilla
2.6 kernels quite competitive with RT-patched 2.4
ones, at least
on the
machines I was running at the time (all
uniprocessors).
The
very early 2.6.x kernels were another story. :-)
