For the Agda code, @nad observed a performance increase from hashtables 1.2.4.2 to 1.3, see:

He reports that this fixes a performance regression for him, but does not pin down where the regression happened.

Also, it seems that vector-hashtables outperforms hashtables by a slight margin, so we are switching.

I thought I let you know, possible actions could be:

  • Document more clearly the quite substantial performance gap.
  • Investigate its reasons.
  • Point to vector-hashtables.
