Yes, I can confirm that 2.10 (and 2.11) seem to use a significant amount more
memory than 2.8.
AFAICR, 2.8 predates your changes to the pagebreaker; we keep all of
the scores in memory now, which will signficantly increase memory use.
However, it would be nice to know some more useful facts about the
memory use.
Here are some tips:
- -ddebug-gc will print statistics of live objects in a file. Look at
this to see what type of objects are using most memory
- -dtrace-memory-frequency will sample memory use over time. Look at
this to see which stages of the program use a lot of memory
Another useful metric is to know when (which version, or better yet:
which commit) introduced increased memory use.
Unfortunately, I lack the time to investigate this deeply now, and I
would be grateful if someone did a bit of legwork for me.
