I recently (ish) upgraded to Jag from OS9 so thought I'd have a go at some of the OSX only clients. RC5 is no more so I am running SETI, dfold and Fold. However my mac (imac 450 DV) is pants at Fold. It took it 5 days to do one work unit. I suspect this is far too long to be of any use since the work unit will have been resent out to someone else. Shall I just pack it in and go with SETI and dfold? It might even make my computing experience faster.

Are all three clients running at the same time on one CPU? I seldom go past 2 clients per CPU, going higher risks overflowing the cache and putting pressure on main RAM bandwidth.
If Fold is running by itself, 5 days on a G3 450 is most unusual. Fold is not altiveced yet, and my G4 350 never goes past 3 days. Usually, I complete Fold units in 12-24 hours, your G3 450 should manage 8-16 hours per avg work unit.
Fold runs best as the CLI version, or as GUI with the protein NOT displayed after starting the client. Also, Fold should not be interrupted constantly, it drops incompleted work frames when interrupted, so it should go as long as possible in the background (or overnight). This implies that the screen saver version will be super inefficent, but I have not benchmarked it to find out for sure.

Aye, I thought I'd run all three on one cpu. Give the little thing a run for it's money. It does cope quite well considering I'm often doing a ton of other things at the same time, credit is due to OSX here.
I'm running everything as CLI, I guess Fold is struggling with everything else that is going on. SETI and dfold (and RC5) seem to cope much better trickling along in the background. My mac spends most of the day doing knack all since I'm away at work so there are a fair few hours when I'm not getting in the way of it's distrbuted computing efforts.
Think I might drop Fold for now then, before my computer drops me

uh, it's counter productive to run more then 1 DC project on a single proc unless you have SMT (yes, I was actually thinking about this while driving home from work(which was 5 mins ago)).
f@h is time dependent. It sounds like it will be fine, if you are just running it. Otherwise, it is the equivalent of a 150MHz G3 proc, assuming you don't ever touch the machine, and that doesn't count for the tons of cache misses that you get for doing that.

What is SMT?
