plz help me fix lags

Hi all! I have a new modern computer, but starbound sometimes starts to lag a lot. I have mods for optimization:

Elektrolite - Fps Improvement,
Elektrolite - Fskip Addon,
Parallax Compression (FPS Improvement),
EVEN-Even MORE Optimized Optimizebound!,
Quest Manager Optimizer (FU),
Starbound 20 Thread Edition.

but sometimes severe lags still occur. What could this be and how can I fix it? Thank you
