Managing InDesign performance for large documents used in SaaS/CRM workflows

Hi everyone,

I’m working on InDesign documents that are part of a broader SaaS/CRM workflow at Gohighlevele CRM , where we prepare long-form assets like onboarding guides, user manuals, and marketing PDFs (150–250+ pages). These files include a mix of styled text, linked images, tables, and repeated components via master pages.

Over time, the document starts to slow down — page navigation becomes laggy, link updates take longer, and PDF exports sometimes take significantly more time than expected. The assets are optimized and linked (not embedded), but performance still degrades as the file grows.

I’m curious how others handle large, production-level InDesign files in professional environments:

• Is it better to split documents and merge at export stage?

• Are there specific features (tables, nested styles, anchored objects) that tend to impact performance at scale?

• Any export or document-structure best practices that help keep files responsive?

Looking for practical, real-world advice from those managing large documentation or product-related content in InDesign.

Thanks in advance.
