Broken: 2.80 (sub 35), branch: blender2.8, commit date: 2018-12-08 17:06, hash: e79bb957fc3, type: Release

Short description of error
Poor performance when editing hair system using particle edit mode.

Exact steps for others to reproduce the error

  1. Open FurBall.blend (attached) using Blender 2.80.
  2. Switch to Particle edit mode.
  3. Use any editing operation (e.g. Combing). Observe how slow and unresponsive it is.
  4. For comparison, repeat steps 1-3 using Blender 2.79b. The performance should be several times better.

@Brecht Van Lommel (brecht) who to assign this to? I'm unsure if this is a drawing (clement) issue or particle issue.

As pointed out in T60373, if you turn of interpolated children particles it becomes a lot better (but not as good a 2.79 still)
