For slow form load times, reducing the number of fields (especially lookups and complex controls) is the primary recommendation to reduce the metadata payload and rendering time. While workflows trigger on events, the initial load is most heavily impacted by form density.

For overall slow system performance, inefficient cascading behaviors (e.g., "Reparent" or "Assign" set to "Cascade All" on 1:N relationships) can trigger massive background asynchronous processes or synchronous locks when records are modified. This affects the entire environment's throughput. Changing security roles to Business Unit access is a security/visibility configuration and does not inherently resolve general system latency compared to optimizing database-level cascading operations.
