New to paper and seeing severe lags - help with timings report

I just recently moved from spigot to paper on a barebones installation with one plugin (chunky). I’m running it on an Amazon/AWS Lightsail instance with 2gb vram with 1280M max allocated for a user community of 6-8 players, max. Most days it’s just 3-4 of us. With 3 users earlier we started seeing severe lag.

Timings report is here .

I’m using chunky right now to pre-generate chunks for world & world_nether. Any other suggestions?

Ok, ignore this request for now. Using the advice given at https://www.spigotmc.org/threads/guide-server-optimization�� and seeing if that helps.
