Memory and Lag

Was doing TNA just now, and was having bad lag. My FPS was in the toilet. There were several points where I had 0 FPS. To make it worse, I was stuck in a memory loop where my memory usage would rapidly increase from 80 something percent to 95, then at 95 the game would lag and memory would go down to 80 something again, so constant flat out stopping. Keep in mind, I brang my render dist. down to 8. I used to have it at 64 (thanks Bobby) pre-fruma when I had upwards of 100 FPS, but Fruma I dropped it to 16 because more players=more lag, and just now before my second TNA run to 8.
I've been using Cull Leaves, Entity Culling, Ferrite Core, Krypton, Lithium, and Sodium to help thusfar. Vsync is off, render dist=8, sim. dist. is the default, 16 gigs of ram. Any settings/mods that could be changed to make this better?

 

Bobby is known for memory leaks, as I've heard. May I suggest swapping to voxy?

 

Yup, that did the trick. Still haven't tested it in a raid, but flew around wynn to test it (conveniantly mapping all of Wynn's chunks) and the Silent exapanse and no problems yet

't worked!
