Sure. You can use it as a benchmark for all the other things that are
slow in KiCad too :D

Things I have found to be irritatingly slow with this board, that might
be worth looking at:

- Ending routing operations on a highly populateld net, like GND.
  Seriously, just try drawing a trace on ground, and see how long it
  freezes after each segment is placed!

- Netlist generation. I had a go at rewriting the algorithm for this
  (it's O(n^3) and doesn't need to be...) but didn't get very far with
  limited time.

- Netlist import. I optimized this a bit with the bounding box
  memoization, could use more.

- Track clearance check. The other parts of DRC are reasonable, but the
  track clearance check takes over two full minutes on everything I've
  tried it on (except my nice workstation at $work, where it takes
  1:45...)
