I run a PB G4/400 384MB 10GB OS 10.3 (Panther) I usually run Mail, Safari, Carrafix (app to control bandwith) and BitTorrent (Filesharing) simultaneously. Occassionally I run Photoshop and Golive additionally as well as other heavy duty tasks, like watching a movie via VLC a.s.o. When I was running Jaguar I read on the net, that Panther was supposed to be faster than Jaguar - even on older machines like mine. So I gave it a try (copying my existing OS on an ext. drive first - as emergency backup) and voilà ... it really runs much faster and more reliable. I think it has much better memory handling (i have a little app telling me how much RAM i have left unwired/free, 'cause i just have 384 .. which is far not enough) Safari can be a pain and a real memory eater .... especially after it has been open for a while. there are lot of other projects out there (like firefox), but i still stick with safari, i restart it some more often ..... after the last update to 10.3.4 apps are opening faster and safari got a little better i think (behaviour-wise) all in all ... computer start-up time is faster (35 seconds), shut down time is way cool with under 10 seconds i think this will be the last essential OS update for my G4 - but I am really happy with it running like it does ..... so my recommondation is a clean install of panther =) On Jun 14, 2004, at 12:25 AM, Gary Mark wrote: > Okay here's what I'm running: > > PB G4/400 640MB 40G OS 10.2 (Jaguar) Usually run Mail, Safari, Acrobat > Reader and Graphic Converter simultaneously and others on occasion. > > Lately, Mail and Safari have been 'spinning the hard drive' and > spinning the beach ball between requests.
