Performance problems with marker creation in an custom editor [message #1719849]

I'm creating error and warning markers inside of a custom Eclipse editor. The markers are created within an error listener based on the ANTLR parser generator.

The bottleneck however is the creation of markers if many errors or warning are detected and created.

It significantly slows down the performance of the editor.

How can I speed up the marker creation?

Would it be wise to limit the amount of markers?

Or do I need to refactor out the marker creation in a job (collect errors in the listener and then create the markers in a Eclipse job)?

Any advise is appreciated.

Each time you create a marker, a ResourceChange event is sent. If you
create lots of markers, you should do this in a WorkspaceJob so that
these notifications are batched. See here:
