Comment 4 for bug 1813038

While trying to use this patch with 5.1 branch, I noticed ~2-3x slowdown while moving interf_u board (opengl canvas, ratsnest disabled), compared with a similar debug build without the patch. It takes 434 vs 166 ms to update footprint location.

Does anyone experience something similar?
