Just a simple observation. Your computer is pretty old. A Dual
P2 at 300MHz might have been a trick piece of hardware about 6 years ago,
but now it's pretty much a relic and it doesn't even run Linux 2.4 very
well. I know I have a P2 at 350 doing firewall duty. I'm guessing it's
probably running a particularly crappy Intel chipset known as the 440GX
which at the time was cutting edge, but has a lot of legacy PCI
problems. Remember PCI is up to 2.3 spec now and your old box is
probably 2.0 if you're lucky. There were a lot of problems with
interactions between ISA and PCI slots back in the day that were only
solved around the 2.1 time frame.
While the actual CPU of the system may not be getting much of a workout,
I bet the PCI bus is, first transferring all that data around and
secondly by running your hard disks at UDMA 33 at best. Try this test
hdparm -tT /dev/hda
Are the numbers any good ? Above 16MB/s ? Probably saturates the
system bus when it does that too. Remeber at UDMA33 your box is using
the bus 3 times longer than UDMA100 to transfer the same data. That can
Dual processors only makes the whole situation worse, since the P2
wasn't particularly good at SMP and especially not on that chipset. I
have an old Dual PPro 333MHz and it's a dog so I know what I speak of.
You would probably be better served by dropping $150 on a used P3 at 800MHz
running a solid chipset like the 440BX rather than trying to make that
particular dog hunt.
Just my 0.02c
btw, how long did it take you to compile mythtv on that box precisely ?
All night ? And I don't even want to know how long it took you to
install an OS :D
