When searching for common strings in a large file, clearing the search can take a long time because of the onDidDestroy listeners registered on individual markers. Currently, Atom itself uses these listeners, but when atom/atom#13516 lands, we will no longer need them, which will significantly improve the responsiveness of find-and-replace.

As part of testing that PR, I fired up this package, and I noticed that it prevents the performance improvement from taking affect because it also uses decorateMarker with individual markers. Have you looked into switching to the more performant TextEditor.decorateMarkerLayer API?

This does not seem to be possible. Each marker relates to a separate linter message. We can't group them into a layer.
