My first guess would be about 25 Megakeys/sec, which would be about 8000 blocks/day.

What I want to know is who has the quad-866, (see http://n0cgi.distributed.net/speed/q...ll&multi=1 ) and more importantly why won't Apple sell THOSE?
If you put a bullseye on yourself, don't be surprised when someone takes a shot at you.

The #s on the 1GHz are 10,588,176 keys per sec, and that's for each proc.

My dual gig benchmarked at 20.79 Mkeys/sec, but the best it's done in real life is 20.41 Mkeys/sec.

I'll second the guess that a dual 1.25 could do 25 or 26, if my calculator doesn't lie.

Anybody got one on order yet?

doesn't say good things about the new G4s.

I wonder if RC5 cares about memory bandwidth, ir whether it all stays on the G4 card, no shuffling between main memory... I dunno how it works anyway.

Nope, RC5 could care less.
It loads into L1/L2 cache and runs from there.

I'd benchmark on the dual gig with seti, but I was getting mean looks from how long I spent on it doing everything else.

Oh, just noticed that I posted as unregistered.

Maxkeys can be found by opening a cli window, them do:

sudo shutdown now

Then cd to your applications directory and cd to dnetc
and then do:

./dnetc

And watch it. With the gui shut off the actual kkeys processing
on a 1.25 gig system could be significant cumulatively.
