This may or may not address your issue of lessening the frequency of the lag when loading tables, and you may already be aware of how to manage the list of sections you are compiling, thus reducing compile time. A few months ago, I was made aware of a way to facilitate what sections of my project are compiled, particularly useful if/when I need to do so repetitively to test adjustments in my project.
I have used brookter’s method to great affect on countless occasions to reduce my compile time from an 8+ minute compile cycle to just over 1-2 minutes, saving me much appreciated time to correct my mistakes and continue working on writing rather than coding.
Apologies if this is not what you were looking for; happy-to-help if it helps!
