Yes.

I got the terminology from gnus itself.... when I open a large group
After showing a message about generating the summary buffer, it shows
a message of `Hiding all threads' and then a count usually only
displays the thousands.

I do realize that groups of that size are really really slow.
I have some experience in that area.

However unless the `hiding all threads' message is misleading and
doesn't really have anything to do with what is happening, I can see
the wait growing longer by watching `hiding all threads'; 1000 ...
...2000 ....3000 the waits between are relatively short but after about
4000 the waits between ouput grow exponentially.  Getting up to 7/8
thousand the wait between 7 and 8000 is quite lengthy.  I haven't
timed it or I'd post the times.

That's what gave me the idea of cutting out the thread hiding.... Also,
must of what I do in there means I have to SHOW threads anyway `T S'
so I have to undo the Hiding anyway.

Writing that made me think it might be a setting of my own doing.

Can one set how threads are displayed when a group is opened?
