- Description
- The three columns show, respectively, total time, user time, and system time. "Main promote" indicates promotions from generation 0. "Internal promote" indicates when an attempt to promote from one generation to the next causes promotion of the higher generation, to make room for the objects from the lower generation. "fixup" is a part of the compaction and promotion process.
