No not really. With a lowlatency kernel I can barely run my audio
interface at 8 / 3 @ 48kHz which works in a bit more stable way with a
RT kernel. I typically run at 64 / 3 and then xruns pop up faster with a
lowlatency kernel compared to a RT kernel.

You write:
"But in testing with Enlightenment, also killing all unnecessary
processes, it really appears to make very little difference to how
firewire interface performs.

Running Mixbus 2.5, 8 mono trx, 5 Harrison plugins (EQ, master EQ, etc).
Older laptop... Sony Vaio dual core 1.6ghz, 2g, firewire Maudio solo.
Disabled ACPI stuff, wireless and so forth. 256 / 3 is barely stable
with plugins not running w/ record."

So you're using FireWire, in that case the FireWire host controller
chipset is key, maybe you could post the output of ffado-diag. Also
getting the IRQ prios right can make a huge difference when using FireWir=
e.
