Notes & changes
Occasional notes from keeping a small setup running.
Housekeeping
- Log rotation
- Weekly rotation with eight kept generations turned out to be plenty; the
compressed archives never exceeded a few megabytes.
- Certificate renewal
- The renewal itself was never the problem. Reloading the server afterwards
was. A deploy hook fixed it for good.
Things worth measuring
- Round-trip time on an idle link
- Useful, but it says almost nothing about throughput. Measure both or
neither.
- Buffer sizes
- Worth checking before blaming them. Multiply the bandwidth by the delay
first — usually the numbers are nowhere near each other.
