This is covered by bugzilla.eazel.com bug 6792.

The CPU utilization is Nautilus getting the top left text for the icons and
the directory sizes. These can both be turned off in the Speed Tradeoffs
part of Preferences.

The problem where the window is "pretty much un-responsive" during this time
is something that I haven't heard about before and haven't noticed in my own
testing. Maybe you should write a bug report about it.

This is covered by bugzilla.eazel.com bug 6793.

Maybe you should write a bug report about this. I don't think we have one
about this issue. Bug 6794 is related, but not the same thing.

Related to bug 6795, but might be worth filing something new.

This was recently addressed. If it's still slow in HEAD, then we have
another problem and may need to reload our old bug report.

We'd appreciate bug reports about both of these problems.

Yes. Not sure if there are bug preventing this from working, but both notes
and emblems are indexed by medusa (both are stored in metadata).

Good suggestion. Could you write this up as a bug report?

Definitely a bug, not a feature. Not sure if there's already a bug report on
this or if it's already been fixed (not sure what version of Nautilus you
are using either).
