Hi Cheskiefisch,
For me the main issue was having multiple search requests to slightly different datasets, which are being handled by Bubble in a serial matter, even worse when one result is being used as a condition for a followup search.
Something which probabaly is not a best practice is I ended up saving the specific personal data the user needs on page load in a thing and made that page with that data available for the user. That actually shaved of multiple seconds.
I might sound like a broken record as I already shared this link today on the forum but the following forum post provided me with a lot of knowhow ‘how to up the performance’:
Cheers!
