So far, so good.
However since a few weeks 6-CURRENT interactivity under I/O load isn't
what it used to be. Uncompressing jdk14 makes the system slows down
heavily, mouse pointer jerked and sound system chopped.

I was hoping that ULE could help however it didn't improve much more
than 4BSD. I suppose there's something else to tweak in order to have
good interactivity under I/O load ?
