I do experience massive lag sometime and there is FPS drop and entities increase by nearly 800 in matter of secodns.... any ideas?

800 entities is nothing. Server saves every 5minutes or so and sometimes its thousand+ even more or less it's completely normal

Massive lag isnt normal and 800+ ents a second? You realise thats over 48,000 ents PER MINUTE? and over 240,000 ents every 5min? My 500x server dosent even see 240,000 ents in a 2 week wipe cycle

I agree, 800 entities in a matter of seconds + fps drop in same tame down to 3fps isnt normal, players also get kicked (eac) and can not re connect.  I need then manually stop server and start. It will also do not react to any command via console.  I think betterl loot is doing it as thats the only change I made recently.  I changed back to magic loot last night, no complaints so far . Razor , I had procedural map on one server and custom map on other. 60 plugins ish, and server info did not show anything suspicious same as full performance report. I really like better loot as can specify every single box. What other plugins does same thing?

Miesku message me on discord @ Razor14150#7265 and Ill help you get things up and running stable

Got issue again with fps. Seems related directly to number of players connected . Noticed some crashes lately and started to look into things . I cap my fps at 60 but they drop down to 1 and server crash. I have moded servers but for test I unload all plugins so no fault at plugind side, I have about 30 players online, 85k entities and fpr drifting between 5-20. When I have no players at all it will kick to 600+ when uncapped.  When I load/unload my plugins it does not make difference at all. Running it on linux.

Thanks for help!
