[BUG] FYI Spawn.Json default values create heavy load per player

ISSUES NOT USING OUR TEMPLATE WILL NOT BE CONSIDERED AND WILL BE CLOSED!
Describe the bug
Wide use of "perplayer=true" instead of "perchunk=true" in spawn.json will cause escalating performance issues as the number of players running the mod pack increases.
To Reproduce
Steps to reproduce the behavior:
Start server
Set the nether, beneath, mythril, full suit armor achievements.
Have 1 player at a time login and observe CPU load rises.
On fairly powerful server ("Gold" at serverminer supposed to run 60 players) even mining gets difficult at three players with these achievements completed.
Expected behavior
Stuttery mob movement. Difficulty mining as blocks fail to mine.
Very large numbers of mobs spawned when multiple players are close together.
Screenshots
If applicable, add screenshots to help explain your problem.
Info (please complete the following information):
- Modpack Version: Rebirth of the Night-2.76.2.zip
- Server or Singleplayer: Server
- Version the world was created on:
Survival
Additional context
FIX:
*** Simple:**
Backup Spawn.json, then change all occurrences of "perplayer=true" to "perchunk=true"
*** Advanced:**
Modify a few select mobs (such as "hungryzombie") back to "perplayer=true". This will allow some scaling but won't overwhelm the server with hundreds of mob spawns.
I recommend this be integrated into the modpack but in the advanced form where some mobs scale but most use standard minecraft mob cap behavior.
Hope this helps! Made a huge difference on our server.

Note- it appears one of the developers has seen my post about this on Reddit and responded.
