Delays in opening very large messages are somewhat routine.  Mutt
opens them instantly because mutt is rather stupid and doesn't do
1/100th of what Gnus does with them.  Consider that e.g. Gnus is
seeking emphasizable text (*bold* _underline_ /italic/) text to toy
with, hunting for URLs to highlight, examining them for embedded
uuencoded data, and Lars alone knows what else.  Each of these
operations has to massage the entire message body.

Granted that a minute seems rather a long time.  But then most of this 
kind of processing is being done by regexp search followed by property 
hackery and so forth -- not really the fastest-acting options around,
usually needing a fair amount of interaction with the X server as well.

I don't believe there are any particularly new sources of slowness in
p0.95.  If you think there might be, I suggest you revert temporarily
to an older version (say, around the p0.84 range) and compare timings.
