merged 1 commit into from Jul 29, 2020

@rgacogne rgacogne commented Jul 29, 2020

Short description

It makes a noticeable difference as soon as the number of backends in a pool increases to more than 8 backends, and a huge difference when there is a large number of backends.


I have:

  • read the document
  • compiled this code
  • tested this code
  • included documentation (including possible behaviour changes)
  • documented the code
  • added or modified regression test(s)
  • added or modified unit test(s)
