The game does try to draw wires that have been made completely transparent: if you want to prevent them from being rendered, you can enable the "hidden in-game" setting.
However, I'm afraid that probably won't help you solve your problem. None of the things mentioned here use much memory, and memory usage isn't really related to latency in multiplayer. The problem here is probably the framerate (= the game running slowly), not latency. The latter is not affected by rendering in any way, because the server doesn't render anything and the networking logic runs separately from the rendering logic. And in general, rendering is usually not the bottleneck, it's all the logic that's needed to update things such as the signal components and lights.
Here's a couple of suggestions on improving the performance of the sub:
- You can use the console command "showperf" to get a rough idea on what's causing the performance problems. If the "draw total" value is much larger...
