Hi, it getting troubles with tps on my server in BlockBreakEvent is causing much lag, some tips to increase tps and reduce lag.
Use Spigot timings to find out what's taking most of your server's resources. Also, you never want to reduce your TPS, you want to increase it
Post spigot timings and your plugins. If blockbreak is lagging, some plugin is probably doing really dumb stuff any time anyone breaks a block. (badly coded plot or security look-ups?)
