Interesting. It doesn't take 3 seconds on my system (Intel(R)
Pentium(R) D CPU 2.80GHz) but there is a noticeable delay using C-n to
move from =* Other= to =* Closed issues=. However, using C-cC-n to move
has no delay at all and moving backwards (either C-p or C-cC-p) also
exhibits no delay.
I have noticed significant slowness in some of my own files lately when
including babel source code blocks, especially latex ones. But I
haven't been able to reproduce this slowness predictably enough to
instrument it and hence report it in any useful sense... still
experimenting.
