How can I regain responsiveness?
Since Lion, responsiveness of my Macbook Pro (15'') has decreased dramatically.
For instance, I double-click a JPG file - then 5 seconds nothing happens - then Preview shows it, but it also gives me the beach ball - another 5 seconds, unti I can finally do something.
And this happens so often, with so many trivial actions on my Macbook that it really adds up.
Is there anything I can do to make it more responsive?
(My Macbook is brand-new, by the way.)
