Slow diagram performance

Laggy canvas, zoom stutter, and browser tips for large diagrams.

When to use this

Use on large festivals diagrams with hundreds of devices or huge underlays.

Improve performance

Reduce underlay image pixel dimensions before upload.
Hide unused ports on dense devices.
Group and collapse subsystems where possible.
Close other heavy browser tabs — diagram canvas is GPU/CPU intensive.
Prefer desktop Chrome or Edge for largest projects.

Large diagrams

Very large device counts and connection webs slow editing — split into zone diagrams or simplify for master overview plus detail zones.
