system issues
- Linux / Linking - relocation processing is very slow two possible ways to fix that
- re-ordering symbol & elf hash tables to improve cache locality, lots of good & simple ideas here.
- -Bdirect implementation [1] - gaining little traction.
- 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
