speeding up rescans

[aliasname]

likely Simon knows the answer but perhaps someone else also knows.
I recently was in need to do some rescans more often due to fiddling with minim settings. Then I came across the Logging level and tried "Trace" getting a quite good idea about what happens.
Now I see lots of lines in the form:
main: adding file tag XXXX=yyyy

And there's plenty I know Minimserver nor a control point nor a renderer must be aware of. Since so the question springs to mind if there's a way to skip some of these? Would that speed up rescans?

And what's the best way to make minimserver skip them?

To prevent just giving the hint to delete these information from the embedded tags, no I need that data for other software whocj also utilises the same collection.
