Running it on a PB 15" 1.67 with a 100gig ST910021A HD.

Noticing lots of disk access clicking since upgrade. Spotlight is finished its indexing so that's not it. It's nit the clicks of death indicating a hard drive failure. I know what that sounds like.

Anybody else experiencing this?

On my 12" PB 1.5 it does a lot more accessing mainly with Spotlight, which also seems to slow down the longer the machine is on. Right now on fresh startup, I typed "default" without quotes in the spotlight menu, and it pretty quickly gave me results for the whole word. In an hour or two I know it will chug finding results for de, def, defa and so on. Makes Spotlight much slower than in tiger on this machine.

For me Spotlight is running much faster and accurately in 10.5

Maybe it is the new hourly Time Machine backups...
