pavel's quick benchmark
This one actually has a huge advantage: factor seems to be part of default installation, so it is easy to run on all machines down to sharp zaurus.

It also shows just how slow those embedded cpus are. I always assumed that arm@400MHz was approximately as fast as pentiumMMX@200MHz. ... that's quite far away from truth.

root@amd:~# time factor $[65863223*65863159]
4337959928701457: 65863159 65863223

amd: 0.591 s
eee @ 630: 1.673 s
eee @ 900: 1.858 s ?!
arima: 0.536 s
hobit: 0.376 s
zaurus: 21.99 s
kohjinsha: 4.062 s

Surprising notes here: Asus eee is much faster than kohjinsha. (In fact, eee has pretty cool CPU, it can compile kernel in like 15 minutes, unlike kohjinshas 90 minutes). And even kohjinsha's geode@500MHz is 5 times faster than zaurus... So zaurus is more like pentium@100MHz.

And now... What's the best and the worst result you can get in pavel's benchmark? Does someone has 386sx still running? Or will some ARMs be even slower? And is there anyone with those pentium extreme's at 3GHz?

	It looks like this essentially tests the performance of division, which makes this arguably not a representative benchmark. My 486 firewall machine gets this. I think it's a DX2/66 but I don't really remember $ time factor 4337959928701457 4337959928701457: 65863159 65863223 real 2m2.489s user 2m2.150s sys 0m0.340s (Reply to this)(Thread)

	If this tests division performance, it's no surprise ARM gets poor results - they don't have a divide instruction. (Reply to this)(Parent)

	slowest machine (Anonymous) 2008-04-30 09:09 am UTC (link)
	...so far is m68k at 25MHz, I got details via email. It took 133 seconds. (Real time does not matter here, as machine had background load). That's approximately 1000times slower than fastest machine around.
