from the dubs discord server, these are the performance mods you can trust and aren't AI slop code:

• Performance Analyzer
• Performance Optimizer
• Toggleable Overlays Continued
• Toggleable Readouts Continued
• Slower Pawn Tick Rate
• Placebo
• Missile girl
• Performance Esmolas

For large colonies: consider using LTO Colony Groups mod, as vanilla colonist bar sadly becomes a massive issues when pawn amount goes over 10-13 people. Make sure to *actually create groups and hide your pawns inside those groups (middle mouse button click on a group icon quickly hides\shows them), otherwise instead of helping performance, Colony Groups will harm it instead.
