DHS causes huge lags and eventually stops my server

[03:16:37] [Spigot Watchdog Thread/ERROR]: The server has stopped responding! This is (probably) not a Spigot bug.
[03:16:37] [Spigot Watchdog Thread/ERROR]: If you see a plugin in the Server thread dump below, then please report it to that author
[03:16:37] [Spigot Watchdog Thread/ERROR]:       *Especially* if it looks like HTTP or MySQL operations are occurring
[03:16:37] [Spigot Watchdog Thread/ERROR]: If you see a world save or edit, then it means you did far more than your server can handle at once
[03:16:37] [Spigot Watchdog Thread/ERROR]:       If this is the case, consider increasing timeout-time in spigot.yml but note that this will replace the crash with LARGE lag spikes
[03:16:37] [Spigot Watchdog Thread/ERROR]: If you are unsure or still think this is a Spigot bug, please report to https://www.spigotmc.org/
[03:16:37] [Spigot Watchdog Thread/ERROR]: Be sure to include ALL relevant console errors and Minecraft crash reports
[03:16:37] [Spigot Watchdog Thread/ERROR]: Spigot version: 4533-Spigot-7c52c66-e703c03 (MC: 1.21.8)
