"All My Files" option in Open/Save dialog get 100% CPU on Mountain Lion for a couple of minutes?

How to solve this?

Mainly this happens twice: once before drawing anything on screen and once again after displaying the files.

After about two minutes you can use the dialog, but the problem reapers every time you click on All My Files.

I do have a SSD+HDD setup on my machine. Console does not say anything interesting.

  • Do you know what process is taking up 100% CPU? Also, do you have any idea how many files? – jmlumpkin Aug 22 '12 at 12:23
  • Same here - mainly when opening that dialog from within Safari/WebKit. – magma Aug 29 '12 at 13:26
  • It's not a problem related to the number of files and the CPU is got by the app doing the file opening, whichever it is. – sorin Aug 29 '12 at 16:41

    The same thing happens to me in every application on Mountain Lion. – Lri Sep 3 '12 at 7:09

    Do you have a lot of version control repositories? Excessive git/hg metadata can bloat Spotlight. Possible information in this question – sjbx Sep 10 '12 at 12:23

This might be caused by the general slow spotlight problems with OS 10.7.5 and 10.8.2. What version of Mountain Lion are you running? How long has this been a problem? If you're running 10.8.2 you might try this workaround.
