Someone on the Debian-User mailing list recently mentioned a kernel patch
called irqtune. It supposedly can increase throughput over a serial port
by up to 3x. It does this by allowing you to increase the priority of the
IRQs for the serial ports. The web page for this patch is at
http://www.best.com/~cae/irqtune. It also mentions some things that are
currently being done wrong in the kernel regarding interupts. Can people
smarter than me look at this page and verify if this is valid or not? If
it is, can this patch (or some of the ideas from this patch) be
incorporated into the official kernel release?

Thanks,

Gerry
