In the old days I had Opis, I think that's what it was called, and it would scan my world and say what block / tile entity was causing lag and it's x/y/z coordinates. Made keeping lag down a breeze, up until Opis broke and started to cause a massive number of wither to spawn in nether fortresses. I was told by a friend (who has his own mod pack and runs his own server) I was one of the few rare people to experience that bug. Jee, makes me feel special. >.< Anyway, forward to 1.10.2 on the Direwolf20 1.10.2 pack, with a couple of mods added (Like Mekanism), and as of late my machine room has been getting laggier and laggier and laggier, even though I do have 4gb allocated to Minecraft and I have 16gb total system memory. Also running Foam Fix which also helps. When I got Draconic Evolution up to the point I have a Tier 7 energy sphere (and surprisingly the chamber I have it in is mostly lag free) and switching over to the DE Wireless Relays and other power transfer systems I've picked up all the power conduit and Mek power cables and it's helped a little but it's still pretty laggy. I don't want to have to tear apart my entire machine room to find the one machine that's causing it nether. >.< Any suggestions ?
