I has been my experience that you can kill/abort a "large number of users"
(for example > 1000) "faster" if you don't try to kill them all at once.
We found it was much faster to abort them in "bunches" (say 100 at a time)
and then 'wait a while' before aborting the next "bunch".
The problem is that I can't tell you what the optimal size for a "bunch"
would be, and I can't tell you how long to wait. I believe we waited
"a couple of minutes" and did 100 at a time. However, this data is
"old", the "high-end" machine we were testing on was a 980. Newer processors
with more memory can definitely handle bigger "bunches" faster. So
I gues you would have to experiment.
I would be suprized if the overall result is not the same today. I
would guess that it is still much faster to abort the users in
"bunches" and not all at once.
Sorry I don't have a more concrete answer, but maybe the basic concept
will be helpful in you quest to abort 1000+ users in a "timely manner".
