Comment (by gschoppe):

 To make it easier to review the issue without having to create a server
 and simulate high load, I've created a pathological theme that, when
 activated, should demonstrate the increased loading time. The file size
 was too large to upload directly to this ticket, so I have hosted it on
 google drive:
 https://drive.google.com/open?id=1t0S_yErQXQJZGlgDBu_Uo9UP3xIJvVJb

 The load time should be significant.
