ippiDilateBorder_8u_C1R performing worse on faster Intel proccessor - IPP 2017 Upd 3

We are running into a strange issue with ippiDilate/Erode. It runs fine on multiple dev machines with varying vintage but exhibits huge timing numbers on our production PCs

  1. Dev1- Intel i72700K - 2-3 ms OK,
  2. Dev2 - Intel i7-8700 OK,
  3. Production - Intel i9-7940X - Massive overtiming 30-40 ms for same function

We use other filters without issues on the same PC and timing numbers usually correlate with age of Intel chip speed.

OS - Windows 7, Win 10, IPP 2017 Update 3, static linking

Any ideas what might be causing this

Nikhil, could you give us the reproducer which we will use for reproducing the problem on our side with different versions of IPP, OS and CPU?
