Answer 1

I've this problem recently and in my case I'm using a linux 64bit SO and my android studio was in a ntfs disk. Since ntfs doesn't support executable permition the file fsnotifier64 was unable to execute and android-studio fallback into a compatibility mode that is much slower. The solution was copy the android-studio folder into my home folder that was ext4 and that way i was able to set permitions.
