Hi @erbteilung Thanks for reaching out!
Typically, we recommend breaking out large apps that are slowing down into smaller apps and linking them together with a navigation bar, localStorage, and/or url params.
Our performance doc also has some other tips on improving performance such as being selective about how often queries get triggered & reusing Retool tabs.
This forum post by one of our Retool team members also has some helpful context for performance 
Our team is also currently working on a new and improved way to link different apps together, so definitely keep an eye out for updates.
