ML Slow when launching applications

[chacolo]

Hello,
I just have upgraded my new MBA (2012) to Mountain Lion.
I noticed that the first time I have launched applications (say Reminder, Notes, Text, a new Finder window, a new Safari window), the system became unresponsive for a few seconds.
Is this normal ? (like he is writing some stuffs somewhere ?)
Thanks

Nope, that is not normal. I'm not getting any problem when launching something.

I meant the very very first time (just after the install). After a reboot or so, it seems to be ok.

Right after you have upgraded to ML, spotlight will start to re-index and it can take some time, anything from 5-10min to hours depending on content and the Mac your using.

In that time, things can seem a bit slow and fans might start make a lot of noise. But once it's done, all should be up to speed again.

It's the re-indexing... Since I'm new to Mac, I got worried when it happened to me too, so I checked my Activity Monitor and it was the indexing process. Took about 10 minutes and now it's smoother than ever...
