I looked at the problem:

1) geanyprj act only on "document-open", "document-save", "document-activate" callbacks
2) geanyprj add a lot of TMWorkObject objects using tm_workspace_add_object() to Geany
3) Geany call update_tags_from_buffer() very often.

I think this function somehow reparse a lot of objects because of "update_parent" param. I am not sure what this param actualy mean but if I change function this way performance is back to normal (I don't say we need to change it, it is just research):
