I just finished the proof of concept to generate a pigmen farm. I will be working on it over the next few weeks to turn it into a true grinder. Once this is done, a similar concept will be used to create a mob grinder in the very near future. The "Gold Grinder" will be back bigger and better than ever with far less lag! No portals were used in this creation so there will not be portal lag from over 2,000 portals that was used previously. At present I am achieving 186 FPS in this area.
