Tried this with 0.6.8.2-1 from Sid/Wheezy today. My strace just
counted 195 stat64() for this.

Most package list files got only 1 to 4 stat64() calls for and despite
having wheezy, sid and experimental as well as main, contrib and
non-free in there, only one of these got noticably more stat64() calls:

Even with Acquire::GzipIndexes I counted just 243 stat64() calls.
Again all files 1 to 4 stat64() calls except for the ending:
[...]

The additional stat64() calls seem to come from checking if an
uncompressed package list exists.
So this seems to have been improved a lot. Closing the bug herewith.
As I don't know when this has been fixed (or it has been fixed more
and more over time), I'm closing it with the version I tested today.

Do you have Acquire::GzipIndexes set to "true" by chance?
If that's the case, selecting packages in aptitude's TUI is really
slow and it takes several 100ms for moving to the next package on my
EeePC 701 (with a 680 MHz Celeron). Otherwise scrolling is totally
fine for me on the very same box.
See http://bugs.debian.org/697724 for details on that issue.

This seems to be yet another different issue, related to the
dependency resolution as you are changing the relations between
packages with that action.
Please file a separate bug about that in case it's still present.
