We finally have a version of LilyPond that can work with byte compiled
files on GUILE 3. I had high hopes for this, given the ebullient
promises of JIT in the release announcement. The results are
disappointing. GUILE 3.0 is 3% faster than GUILE 2.2; both are about
30% slower than GUILE 1.8

I wanted to look more into the cause of this, and tried to run statprof.

This prints a ton of

;;; (what! #<stack 7f60fbf7fc20>)

lines. Then, the results look like

            97.2% #x221bfb4
                    27.6% #x2215134
                      27.4% #x221836c
                        15.6% #x2215138
                          15.6% #x220ae70
                            15.6% profile-signal-handler at statprof.scm:251:4
                              15.6% #x2212b88
                        6.7% #x2218430
                          6.7% #x220ae70
                            6.7% profile-signal-handler at statprof.scm:251:4
                              6.7% #x2212b88

Is there a way to get insight into what these hex addresses (?) mean?
