[Metal] Performance degradation on iOS devices
To reproduce:
1. Open the GraphicsPerf project with Unity 2018.2;
2. Change Graphics API to Metal;
3. Build and run DynamicVBO, Lights, Materials, Particles, ParticlesCollision and Tesselation scenes on iOS devices.
4. Repeat all steps with Unity 2018.3.0a6;
5. Compare frame time.
Important: let devices to cool down between each run.
Expected result: performance increases or at least remains the same.
Actual results: frame times increase 6-12% in trunk, even 40% with some devices.
Devices under testing:
-iPad Mini 4 (SoC: A8, iOS: 11.4),
-iPhone SE (SoC: A9, iOS: 10.0.1),
-iPhone X (SoC: A11, iOS: 11.4),
-iPad 5th gen (SoC: A9, iOS: 10.3).

Not sure if this should be mentioned here, but there's performance degradation issues for Android builds as well. Just updated to 2018.3f2 from 2018.2 and builds on devices suffered a sudden performance drop.

"Necessary for shipping a final release" - and now we have 2018.3 final and report is still only "Active" ?

Bump - an update on this would be great, especially considering how long this issue has been active for. It’ll get fixed for 2018.4 LTS right!?

Is this going to get addressed/fixed in 2018.3?
