[0.15.2] High CPU use on Linux

Running Debian with graphics drivers from nvidia. CPU stays at 800% while in a game. Works fine under Windows on the same machine. 0.14.23 has a similar problem, but limited CPU use to 600%, and is a bit more playable. 0.15 is too slow to play well. GTX 980, i7-5930K.

That sounds like a configuration/OS issue on your end. Factorio doesn't even launch enough threads to consume that % of CPU.
Additionally we experience no such issues when running any version on Linux internally.

I'm seeing something similar to this, but it's X that is spiking high on a single core. I saw it happen once on 0.15.1, but now I'm on 0.15.2 it seems to be happening near constantly. Never had any issues like this in the 200+ hours I've played in the last month on 0.14.x.
What seems odd is that the game thinks the FPS is fine and dandy, but when this really kicks in I'll be looking at maybe 1FPS.

Seems like I/O waiting state. How much free ram You have? Can You capture result of "top -bn 1" when misbehavior occur?

I don't see a section named "performance issues" or anything similar in the FAQ.

Can you suggest some ways to determine this? I'm not sure what configuration I've changed to cause this.

32G of ram.

This happens immediately after loading a map.

The only thing that I find a bit weird is that X is hitting 80% CPU usage on the main menu immediately after starting the game. Which _really_ shouldn't be pushing things hard at all.
