Customize Theme Super Slow

With Gravity Forms enabled the customize feature of my theme is incredibly slow. It is responsive with GF plugin disabled.

Gravity Forms Version 2.5.6
Total Plus Theme Version: 1.5.3
GF No Conflict Mode is enabled
Had to increase the PHP.ini script timeout above 30 in order to be able to use the customize option
max_execution_time is now 300 (was 30)
max_input_vars is now 3000 (was 1000)

Hello. How is the performance with a default theme from Automattic like 2021?

Almost instantaneous.

In that case, I recommend reporting this issue to the creator of the theme. It’s possible they will need to make some changes to be compatible with the latest Gravity Forms release.
