Hi John,
Do you have a rough idea on how long the page is taking to load for you with the delay setting enabled?
I must say that the load times are not significantly different in my case (using about 10 flexi layouts and conditional logic in most of them) – maybe the issues are unrelated? I have a feeling that the release candidate 5.5.X version was working better for me than the latest stable release?
Cheers, Scott.
