This is really strange - I call the same tag-generation-related
functions as GeanyPrj does so there shouldn't be any difference. Are
you sure that there are the same patterns for both projects and that
e.g. GProject doesn't match more files? That would explain the time,
otherwise I have no explanation.

Is there any way I could reproduce it here? If you find some test case
with e.g. some open source project I could download and test the tag
generation time, I'm sure I can get to the same times as GeanyPrj -
there's no reason why GProject should be slower.

Cheers,
Jiri
