Mermaid Performance

Large Diagrams

Very large diagrams can become slower, particularly with complex layouts.

Instead of creating one huge diagram, divide it into smaller diagrams.

Long labels can make layout more complicated.

Prefer concise node labels when possible.

For production documentation, pre-generating SVG files can reduce runtime rendering work.

mmdc -i diagram.mmd -o diagram.svg

This can also be integrated into build or CI pipelines.
