Network Manager has increased cpu usage in linux player after upgrade to 2018.2
To reproduce:
1) Open attached project
2) Build for Linux
3) Run it and check CPU usage in the monitor or another app
Expected: 0%
Actual: 4%
Reproduced in 2018.2.2f1, 2018.2.3f1, 2018.2.5f1, 2018.2.12f1, 2018.3.0b5
Not reproduced in 2018.2.1f1, 2018.2.0f2, 2018.1.6f1
Not reproduced in Win 10 (identical usage across versions)
Prior to 2018.2.2f1, there was a bug that limited headless server frame rate to 60fps. This was corrected in 2018.2.2f1, allowing headless servers to run at unlimited framerates. Running at a high or unlimited framerate will burn more CPU. Headless servers should set Application.targetFrameRate; see https://docs.unity3d.com/ScriptReference/Application-targetFrameRate.html
Setting Application.targetFrameRate = 60 results in the lower cpu usage observed prior to 2018.2.2f1.
