Plugins that send broadcasts to all players servery lag server

I'm noticing this issue with EvolSoft Broadcaster and Restartme

How can I fix this ?

https://github.com/EvolSoft/Broadcaster
https://github.com/ifvictr/RestartMe-PocketMine

 

Doesn’t lag for my server

 

Yea idk what's wrong with my server, but it's always when a broadcast or restart msg occurs

 

use /timings on

 

Alright I'll try thx
