Amiga benchmarking programs typically bypass the filesystem and
manipulate the raw disk device to do their speed tests. They also
disable multitasking. I suspect that this is so that the Amiga owners
can look at PeeCee owners and say, "Ha! My Computer Is Better Than
Your Computer!"
In any case, the results obtained from benchmarks usually have no bearing
on the machine's real-life performance.
Disclaimer: I'm currently typing this article on my Amiga, which I am
using as a terminal on my BSD system. Don't send lots of cruft about
how fair-minded and non-bigoted Amiga owners are; I've seen both sides
of the fence. Remember that this has not been posted to an advocacy
group.
