# Performance Tips

Supervertaler is designed to stay responsive on large projects, but performance can vary with project size and enabled features.

### Tips

* Pick a smaller **Per page** size for very large projects (the grid shows all segments by default; projects over 2000 segments auto-paginate at 500). See [Pagination](/help/editor-and-translation/pagination.md)
* Keep only the needed TMs and termbases enabled
* If semantic search is enabled, allow indexing to complete

### Quick wins when it feels slow

1. Disable spellcheck temporarily (Settings → View Settings)
2. Close other heavy apps (browsers with many tabs, IDE builds, etc.)
3. Restart Supervertaler and reopen the project

### Large projects

Very large files (thousands of segments) can stress any UI grid.

* Prefer pagination.
* Consider splitting source documents or using multi-file projects.

### If it feels slow

Try restarting the app and reopening the project.

If performance is still poor, note:

* Project size (segment count)
* Whether spellcheck is enabled
* Which CAT format you imported
