00:00 Why are overlays slow compared to text properties?
03:21 Would these optimizations be helpful in a personal init.el?
04:28 What's a good approach for benchmarking destructive operations?
06:06 Do you recommend avoiding cl-defstruct in favour of "pure" lists/vectors?
08:20 Possible to optimize Emacs packages with code compiled from other languages?
10:26 (Q&A logistics)
12:25 What about text properties vs. buffer-local variables to store position cache?
18:40 Followup on earlier cl-defstruct benchmark discussion RE: AVL trees
30:48 Does cl-defstruct have memory overhead/general memory usage discussion
