Dynmap takes 7ms

[StKillReal]

Issue Description: Dynmap takes 7ms and drops tps from 20 to 14-17. I thought it because of full render, but when it finished nothing changed and dynmap still takes too much time per tick

• Dynmap Version: 3.7-beta-6
• Server Version: purpur-2275
• Pastebin of Configuration.txt: https://pastebin.com/cyReWScW
• Server Host (if applicable): Hetzer dedicated server
• Steps to Replicate: See mspt with enabled zoom/updating renders, then use /dynmap pause all and see how mspt decreases
