[...] I did more performance measurements of the byte-compiler with a version where I disabled handling of symbol positions, and not noticed a sensible speed up of byte-compilation. So the slow down, compared to 21.2.1 version, seems to be caused by another change. I must admit that I don't see what actually causes a such performance degradation. Maybe someone else has an idea? Hope it helps. Sincerely, David
