This article applies to:

  • SWG 10.x
  • SWG 11.x

Question:

  • Why do some some pages load slowly with SWG caching kit installed and enabled?

Information:

HOW to fix the issue:

Because it is not an SWG related problem, you must exclude this type of site from caching; add an exception as shown below:
