Unnecessary disk reading activity
-1

As long as it's a Nautilus option in prefs I have no problem with this +1

And not just folders, also on files! One feature I really missed from Windows.

Always a problem when you have lots of files and folders. Nautilus already poops on my folders that have 10s of thousands of image files in them.

OMG, WTF STEVE!!!
Unneccessary disk reading??? Seriously, paranoia. Because you are SERIOUSLY damping productivity when you get a tiny bit of I/O when you are searching through directories trying to find things. (Sarcasm)
+1...

Seriously not Paranoia. Every little bit of I/O we do inside of Nautilus /kills/ us performance-wise. That's why we are very careful *not* to do I/O, and when doing I/O, to do it asynchronously.
Doing this kind of tooltip requires hitting one of the slowest codepaths inside of Nautilus, because it requires a recursive directory scan (welcome to the Hell that is get_deep_counts()).

Oh, a developer.. thats good :) And it also means I'll agree with you awalton however you vote.
But walton, would you agree, that if your mouse is hovering over a tooltip in Nautilus, then you probably aren't heavily using the harddisk anyway (you probably wouldn't be watching a movie, or be doing any realtime activities if you were in nautilus too?).
Would users be do something that actually requires perfect HDD speeds when they are in nautilus?
That was what I meant.. It may be slow, but will it actually affect users productivity?

Plus, it could be made an option couldn't it? If it is slow (which I agree it could be) we could just make it off by default, but easy to turn on

That's not what matters; doing long I/O means doing long I/O, which can really trash Nautilus' performance, which is why it's not to be taken lightly (think about the case where you moused over "/home"). It does do a huge amount of disk access; recursive counts are very expensive, and we're talking about doing a new one every time you mouse over a folder.
But, at the same time we also cache a great deal of information in Nautilus, so the next time you mouse over, as long as the cache is still valid, it's nowhere near as expensive. And if it's coded right, we should be able to cancel the deep count after the user mouses off the file so it shouldn't be prolonged.
I'm not totally against the idea, I'm actually quite apathetic to it as long as it doesn't turn into a huge performance sink (which is what I'm weary of). Like you said, it's easy to turn off with a GConf key for those who don't want it, though including it and turning it off by default is silly. And someone stepped up to work on it, so all the better.

Having just discovered this feature in Windows, it would be nice to have it Ubuntu.
It's worth nothing that Windows aborts the deep scan after some time-out/cut-off. The toolyip displayed is then:
Size: larger than [M|G]B
Folders: Foo, Bar, ...
Files: foo.txt, bar.doc, ...
