Performance
From Apache OpenOffice Wiki
Contents
Known areas for impovement
system issues
- Linux / Linking - relocation processing is very slow
- Linux / I/O scheduling & pre-loading is poor
General I/O & memory issues
- Config mgr - scattered files
- UI configuration - tons of scattered files
- .rdb files - loads of empty space, mmap + random access pattern
Helpful tooling
- Linux/cold-start simulator
- relocstat - dump relocation data
- RTL_LOGFILE - export RTL_LOGFILE=/tmp/foo
- valgrind - debug / trace memory usage
Approaches being worked on
- Config refactor - reduce seeks/files, better caching
- Disk Access
- -Bdirect linking
