delay when quitting digest

Admittedly, my computer is slow in general, but depending on the
circumstances, there is a noticeable delay when quitting digests.
Here's the situation:

Background: I have gnus-auto-select-first set to nil in
gnus-select-group-hook, so I don't automatically get an *Article*
buffer when I enter a group.

Case 1: I enter a mail group which contains a digest, then go to the
digest and hit `C-d' to look at it.  Then when I hit `q', I return to
the *Summary* buffer almost instantaneously.

Case 2: I enter a mail group which contains a digest, read a
non-digest article first (so there is an *Article* buffer around),
then go to the digest and hit `C-d' to look at it.  Then when I hit
`q', there is a delay (perhaps several seconds--the length depends on
the size of the digest), and then I return to the *Summary* buffer,
which now shows the digest in a single *Article* buffer.

First, what's causing this delay?  Probably reading the article from
disk and parsing it for highlighting, etc.

Is there a hook I can set to fix this (maybe so that when I enter or
leave a digest, the *Article* buffer associated to the parent
*Summary* buffer is deleted, or maybe to turn off article highlighting
just for digests)?  Or is there some other fix?  Is there a good
reason to automatically display the digest in an *Article* buffer
after having read it as a digest, or when quitting a digest should the
default be to just go to the *Summary* buffer?
