The computer I'm writing this on is now over four years old. It's
been upgraded some, like most every computer I've owned, but its
far and away the most satisfied I've been with a four year old system.
At the moment I have two web browsers open, this newsreader, two
virtual machines,a media player, dozens of background processes...
and it's not even close to breaking a sweat.
My rule of thumb would be
P4 @ 3GHz (preferably, a cooler-running Northwood CPU)
Athlon 3200+ (S462 minimum, but any later socket would be better)
as minimum machines. I have about four motherboard/CPU combos that
meet those requirements, and any of the four pieces of
hardware is good for day to day usage.
I have a 1.8GHz P4, and the peripheral interfaces and memory are pretty
slow in that one. It would be interesting to test that processor,
in a decent motherboard, to see if in fact it would be acceptable.
Once you get back to older machines based on this architecture
Processor ---- Northbridge ------------+---- Southbridge --- disks
PCI Bus |
+--- Add-in PCI slot
|
...
that's pretty hopeless. Too much traffic through the PCI bus. Tends
to be sluggish.
Something like this
Processor ---- Northbridge ----------- Southbridge ----- PCI slots
Hub Bus ----- Storage interfaces
plus a 3GHz P4 equivalent (at least a single core), and then that is good
enough. The Hub bus can be anywhere from 266MB/sec to 1GB/sec on
some of the older machines with that design.
It takes a lot of bloated software (emulation upon emulation) to
make acceptable hardware, look like crap. I was reading today,
how some tablet or other, was using Java for some key functions,
and, well, I couldn't believe it. That's sheer torture. Java on
overpowered hardware, is almost acceptable. Java on top of
some marginal processor - who wants that ? If you're going to
run older hardware or weak hardware, you want "lean and mean"
software for it. One of the reasons you still like your computer,
is the older OS on it
Even some of the latest Linux distros, are packing a bit too much lard.
It's actually hard to find a good distro with a 2.6 Kernel, where the
emphasis is on a lighter memory footprint.
