Tps routinely drops to sub 3 when calculating large recipes. I've tried to make the individual components to lighten the auto crafting load on AE but it doesn't seem to help. To continue to progress to endgame in the pack it is necessary to be able to autocraft these items with ae2. I suggest installing PrototypeTrousers Ae2 patch (https://github.com/PrototypeTrousers/Applied-Energistics-2/releases) its an OF dev supported patch that helps optimize channel less Ae. All of the optimization changes are server side only so players should be able to connect without need to change any of their files.
