Direct answer
Many server optimizations change game mechanics, not just CPU time. Before enabling a performance setting, document which farms, mobs, redstone contraptions and player expectations it may alter.
How to check it
- Record the software fork/version and a concrete problem visible in a spark profile.
- List gameplay systems that depend on the feature being tuned, such as villager AI, hopper transfer intervals or entity activation.
- Test one documented change in a staging world with a representative farm and normal player movement.
- Measure MSPT and compare entity drops, farm rates, redstone timing and spawn behavior.
What to change
- Prefer fixing excessive builds, plugin tasks and overactive chunks before disabling core vanilla behavior.
- If a fork adds an optimization, read its version-specific documentation rather than assuming upstream Paper syntax.
- Keep a reversible configuration record and consider whether a change is suitable for a technical/redstone-focused server.
Software and version notes
A server can achieve lower MSPT while quietly breaking trading halls, mob farms or combat timing. The best setting depends on the gameplay promise of the server, not a universal optimized preset.
Practical example: Example: reducing hopper frequency can improve a measured storage-room hotspot but change the throughput of item sorters. On a technical server, that may be unacceptable despite lower MSPT. Compare both a profiler result and items moved per minute on staging before treating the tweak as an improvement.

- Get a real gameplay sign-off from players who use affected mechanics.
- Keep the setting only if measurable gains justify documented behavior changes.
