I was testing my (Modded) Minecraft Server for the first time. It has 138 mods loaded and its version is 1.7.10. When I first logged in my server, everything was apparently working fine, but after trying to break a log, it reappeared and after 5~6 seconds disappeared and dropped the wood. When I punch a chicken, it takes around 3 seconds to the hit occur.
I want to know HOW CAN I REDUCE ALL THAT LAG. It's just awful. I'm hosting my server side-by-side with my client game.
My upload speed is 38.88 Mbps
