Hi developers, Some information that may help when looking for LilyPond performance optimisation.
When I converted a (rather large) score I noticed that Lily's resource usage is somewhat strange. Total conversion time: about 10 minutes. During first 8 minutes memory usage slowly increases to 190 Mb. This is not spectacular. During first 8 minutes, total bytes read (that is, read from disk) increases rapidly to 9.6 Gb. This is bizar! Last 2 minutes, reading from disk stops, memory usage increases to 413 Mb, a little high. end result: PDF of 24 pages, 560 kb. Especially the 9.6 Gbytes of disk-io is a major concern when it comes to performance. Luckily most of it is cached (no disk light activity) but nonetheless. If someone is looking for possible optimisations, I would look in this direction too. regards, Hans. ps. version 2.6.3 Native windows, running Win2k _______________________________________________ lilypond-user mailing list [email protected] http://lists.gnu.org/mailman/listinfo/lilypond-user
