Does OS matter in Crackin' RC5?

Hi folks, been away for a short bit (it's good to be back).

Here's what I am discovering:

I've tried 2 different systems (an Athlon 700 and a K6-2 500) with only an OS and DNet client. The OSes are Win98SE and Win2K Pro and a clean install was done for each example. The results are as follows:



System Win98SE Win2K Pro

Athlon 700MHz 2.34 M K/s 2.47 M K/s
K6-2 500MHz 743 K K/s 862 K K/s



This means an extra 130K K/s just by going to Win2K? Has anyone else experimented with this? If so, what were your results and conclusions?

No I haven't yet but I'm getting ready to. Another few weeks (when I get time).

Is that what you Crack on?

ya Win2k is almost always faster for RC5, there are several reasons, optimized kernal, better thread management, etc. In some cases Win2k can actually get a higher keyrate than linux, but i think linux wins most of them.

I switched a couple of K6 processor boxes from Win98se to NT4, and the times were faster with NT. Went from 766K/sec to about 830/sec as I recall...

That's right KGBMan... I use Win2k only because my client runs faster. You might consider a dual-boot if you want to use both Win98SE and Win2k... Good luck!

Unfortunately :)( ), Linux cannot even compete when compared to W2K cracking speed (The Win32 client is better optimized). This is especially true on my Tbird (1GHz) running the Athlon optimized core.

Linux: RC5 - ~3,400,000 keys/s
OGR - ~5,300,000 nodes/sec

W2K: RC5 - ~3,620,000 keys/s
OGR - ~8,300,000 nodes/sec

The W2K client kills the Linux client in OGR. I happen to be running W2K on this machine, so it doesn't matter to me. :)
