So one of my friends and I absolutely love the Tekkit modpack. Just the standard one with the blue rocket picture. We always run into a severe lag problem with the server. We can't manage to make it stay running smoothly after we build like two or three machines with a mediocre base. Both of our PCs are pretty top end for the modern day (2021) so we both have things like 1080TI graphics cards, 32GB of ram, etc. I've been running the server using the software on technicpack.net and allocating upwards of 20GB of ram to it, but for some reason the lag problems persist. In addition, it isn't lag caused by poor internet connection. We both have very fast internet that has more than enough bandwidth to support the server connection. To connect to each other we typically use Hamachi because we don't feel like trying to find another method or port forwarding our routers. Any help would be super appreciated! Since there isn't a way to edit, let me add. We really enjoy making super big farms and stuff. Getting enough emeralds or platinum or whatever it was to make multilayered, max size farms is super fun, but it makes the world unplayable unfortunately.
