Are you a sucker for bringing your server to peak performance, but /tps isn't quite accurate enough for you?
Then hot damn, use jaylawl's TickMonitor plugin for paper spigot based servers! >>> Spigot Link <<<
TickMonitor allows you to monitor your server's MSPT (milliseconds per tick) - which is helpful for finding processes that take up lots of CPU power. Rule of thumb: if your MSPT are below 50 ms, your server should run on *20.00 TPS!
