Personal Modpack Optimization Recommendations

Title, trying to optimize my modpack but I don't know what to do with it. Mod list below, and two Spark profiler reports (one from just being in my base, the second driving a train into the Nether, and ~800 blocks away back into the Overworld.

(TL;DR) Explained below but if you don't wanna read it all, basically I'm having some lag with Create trains, and I do expect lag to build up as I build more machines sadly with Create and Modern Industrialization, which are pretty much two of the four major mods that should be causing any kind of relatively big performance changes/gameplay impacts. Looking for any suggestions for optimizing my game!

Been having issues where the train seems to be moving with some lag (not smooth, stuttering a little here and there), and whenever I go into the Overworld, most of the time my bogeys don't load in unless I go back in and out of the Nether myself, or I rejoin. It's not a rendering issue either, F3+A does nothing, and there is no hitbox for the missing bogeys, they aren't invisible, just not loaded in at all.

The only machines I have running are in Create, which are just some basic things; two level 9 steam boilers, and a double of each basic Create processing machine (e.g. mechanical presser, mixer, deployer, sawmill, rolling machine from Crafts & Additions). I also have my render distance down to 8 and simulation distance down to 6.

For optimization, as of recent I cut down the mods by about 20-30 to go down to around a total of 49 installed. Major mods are Create, Modern Industrialization, Apotheosis, and Sophisticated Backpacks. I also have the usual good optimization mods, like Sodium, ModernFix, FerriteCore, Lithium, and ImmediatelyFast.
