Clear Lag is a script which I've made, the main objective of the script is to remove all the un-necessary entities on your server in-order to keep a stable TPS. I've been using this on my server for the past week and it goes from:
Without Clear Lag: 19.60 --> *20.00 With Clear Lag.
This is a very efficient script and I believe it will help out a lot of your servers.

If you need support with this skript, the best way is to open a PM with me and title it "Clear Lag - Support" and state your issue, I will try my best to help with all issues, Maximum 24 hour wait.
