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?
