Dan,
your critiques of my lack of procedure are spot-on and I apologise. It is likely the primary cause for my current state of disarray, having had 3 machines that I relied on professionally, but did NOT know how to properly maintain, fall apart in various ways over the last 18 months, leaving me with a confused mess of badly-migrated systems and restores over several machines. I'm badly in need of bringing this all back to a semblance of simple useful work-sensible systems and, at least for the moment, pretty well not up to the task.

both the original 2.0GHz G5 and the loaner 1.8  run 10.4.11

Did you clear and rebuild the kernel and system caches after you moved the drives?

and am really surprised at what seems to be its lack of performance... just doing youtube stuff, even without enlarging the playback, it stutters every 3sec or so on playback.

Neither the regular flash player nor perian are memory pigs. And anything over .8 GHz should have no problemo playing YouTube stuff, regardless of the video card.

That the stutter is happening every 3 sec tells me there is something else going on. Something else is running on that cycle, or your network connection is having issues. Errant spotlight indexing is a prime candidate. Use Activity Monitor to check things.

Use a tool such as AppleJack or OnyX to clear and rebuild your kernel and system caches. Then clear out the user caches. Make sure whatever app(s) you're using to play the videos are up-to- date, ditto the codecs. Then do some speed tests and then some traceroutes to youtube...


In the future please provide basic hardware and software configuration information in your FIRST posting. At this point, there are 4 messages from you in this thread and you still haven't said anything about the software environment! We donno what OS is involved, whether it's up to date, what apps, what specific videos, etc... so suggestions that you replace the video card or add memory are totally premature. It makes no sense to recommend expanding memory until you check to see if the memory have is even being used, etc.

- Dan.
