I don't have the original thread any more, but I'm pretty sure it was Fons
as well who explained why this mattered.

It has a lot to do with the native rate of the device and the math involved
at having to achieve the non-native rate.  Some ADCs (like the Delta 1010)
allow you to set their native rate, so running my 1010s at 44.1k was no
problem.  I recently got an Alesis MultiMix16, which gives me 18 channels
of input to the computer via firewire.  I found that if I ran JACK at
anything other than the Alesis' native 48k, performance was awful.  Running
at 48k has been smooth sailing though.
