Why is my computer running more slowly after the snow leopard upgrade?

Did you do a clean install or an inplace upgrade?

I think clean install. I just put the disc in and installed, so…

A clean install would have formatted the hard drive. Here was a good discussion and idea on doing a clean install…

If you can’t narrow down the issue, you might consider doing a fresh install (after backing up your data of course)

Did you upgrade your RAM?

Make sure it is th kryptonited, Blessed memory :-D

I only have 2g so am watching how this turns out. Before I waste my time.

i have a mac mini with 2GB and a Macbook Pro with 4GB and i haven’t noticed any speed changes, plus or minus. I didn’t do a clean install, either, it should be noted.

Are the changes and improvements enough to pull the (very tiny) trigger?

@majorrich i like some of the interface updates, and Quicktime X is very sweet. i use that on my macmini, which i use as a media center, more than Front Row or Boxee. very smooth. it does take up less space on the HD, too. i got about 5GB back on each install.
supposedly, too, there’s some recoding that’s been done under the hood as well, to make better use of the processor.

I’m running Snow Leopard both on my MacBook Pro at home and on my Mac Pro at work. Both of them are noticeably faster at things, although they are not more responsive.

If you’re running Time Machine, it may be that it’s sluggish because it’s backing up a lot of new data; it may also be slow because of Spotlight indexing.

I did an upgrade on my 2.0GHz aluminum macbook with 2GB of RAM and it runs fine. All the 64bit core apps are faster although I do notice that I am generally using more RAM. How old is your Mac anyway?

13 Months. Just out of warranty. Its a gen1 2.4 core duo. I call it the but roaster.
