Greetings. I tried building the lilypond source code from the master branch latest revision (18 Sep 2020) from this gitlab repository <https://gitlab.com/lilypond/lilypond>, and that's accomplished successfully. But when I try to engrave a medium size ly file with myself built lilypond, it costs 35s, as compared, the official lilypond of 2.20.0 costs only about 11s.
I noticed the latest code depends guile 2.2 and the old version depends guile 1.8, can that cause the time cost difference? I followed every step in here <https://lilypond.org/doc/v2.19/Documentation/contributor/compiling>, and I got a huge lilypond binary file (104.3MB), is it a debug building? Did I miss something? For my work, the runtime efficiency is critical. Thanks for any help.
