Hey Guys,

I am running mac on Acer 5745G, and recently updated to 10.6.6, post that I am experiencing a very sluggish system, The UI seems to be responding slowly. Following are things I have already tried but didnt help:

1. Repair Permissions using pfix and touch /S/L/E folder
2. Graphics Kext Update from nvidia's site
3. Repair the filesystem by booting from Install USB

I have currently installed 10.6 on a new partition and upgraded to 10.6.4 and I am seeing the old fast system! Any ideas / Suggestions on How to diagnose what might be wrong?

Thanks in advance.

slice, any idea ?

What idea? Check all.
Check drivers are loaded.
Check speedstep works.
Compare ioregs, system profilers.

After 10.6.6 update I noticed heavy HD usage in the first 5-10 minutes after power on, making the system slow overall.

The solution was preventing Spotlight from searching Windows 7 partition

I tried a couple of things:
- Disabled Spotlight on all the drives.
- Checked that SpeedStepping was working fine - It was.
- Installed the graphics drivers from nvidia website.
- Tried loading / unloading some kexts like VHDA.

All of the above didn't seem to help...

I will try IOREG once and see if there is a diff.

Thanks,
Rock
