Re: Is it just me, or did 21.3.50 get a whole lot slower?

    After pressing "reply" to compose this e-mail, I went to the first
    line of the message and typed "C-n" four times.  I had my co-worker
    time the pause on his stopwatch.  It took 5 wall-clock seconds for
    the cursor to move.

Can you use GDB to stop it while this happens?
If you do that even 4 times you will probably see where it
is spending most of that time.
