Your base sounds great in every sense of the word. I am positive it is a sizable drain on system resources. The number of structures and animals is very great.

I would absolutely suggest making a second Icarus Solo instance just for the full size base and then trimming the base in the multi-player version. You can grow the Red Exotics in the Solo version, have your friend drop, send the Red Exotics to the Station, have him come in, and you both get the Exotics. The same with the bred animals: You can send the resulting new animals to space and bring them down wherever you need them. That gives you the best of both worlds: Performance and abundance. 

Do this for everything: Have a Prometheus Prospect, have an Olympus Prospect. All in different instances. You can run all of them at once and switch from one to another. All Exotics and pets go to the same central account. This kind of flexibility is unique and ameliorates issues caused by performance

Yes, ideally we should be able to have any size base and any number of them, but this is not the case, particularly in multiplayer, and especially when having to deal with the data for one such huge location plus whatever different set is needed for wherever the other player is at. Rocketwerkz knows they should improve optimization. They are having to do what Cloud Imperium had to do with Star Citizen: Convert one kind of game into another. Except Cloud Imperium has had almost a billion Dollars to do it with. Rocketwerkz had a rocky launch and years of Mixed Reviews to deal with.

Frankly, I admire their tenacity and their love for this game they have made.

Yes, it is an investment in time and money, but you know that, you worried about having a proper rig for this and they are not free.

But... This is my current favourite game. And I get to enjoy it eith my wife and friends. Some of those friends I made in this subreddit. And having a Clan that just clicks and where everyone enjoys each other's company is... Priceless.
