Creating an OperationQueue is very straightforward, as you can see. Naming your queues helps with debugging, since the names show up in Instruments or the debugger. The maxConcurrentOperationCount is set to 1 for the sake of this tutorial to allow you to see operations finishing one by one. You could leave this part out and allow the queue to decide how many operations it can handle at once — this would further improve performance.

How does the queue decide how many operations it can run at once? That’s a good question! It depends on the hardware. By default, OperationQueue does some calculation behind the scenes, decides what’s best for the particular platform it’s running on, and launches the maximum possible number of threads.

Consider the following example: Assume the system is idle and there are lots of resources available. In this case, the queue may launch eight simultaneous threads. Next time you run the program, the system may be busy with other, unrelated operations which are consuming resources. This time, the queue may launch only two simultaneous threads. Because you’ve set a maximum concurrent operations count in this app, only one operation will happen at a time.

Using different material instance cause game object not batch

• Using different Material instances causes GameObjects not to batch together, even if they are essentially the same. The exception is shadow caster rendering.

• Batching dynamic GameObjects has certain overhead per vertex, so batching is applied only to Meshes containing fewer than 900 vertex attributes in total.
• If your Shader is using Vertex Position, Normal, and single UV, then you can batch up to 300 verts, If your Shader is using Vertex Position, Normal, UV0, UV1, and Tangent, then you can only batch 180 verts.
• Note: attribute count limit might be changed in future.
• GameObjects are not batched if they contain mirroring on the transform (for example GameObject A with +1 scale and GameObject B with –1 scale cannot be batched together).
• Using different Material instances causes GameObjects not to batch together, even if they are essentially the same. The exception is shadow caster rendering.
• GameObjects with lightmaps have additional renderer parameters: lightmap index and offset/scale into the lightmap. Generally, dynamic lightmapped GameObjects should point to exactly the same lightmap location to be batched.
• Multi-pass Shaders break batching.
• Almost all Unity Shaders support several Lights in forward rendering, effectively doing additional passes for them. The draw calls for “additional per-pixel lights” are not batched.
• The Legacy Deferred (light pre-pass) rendering path has dynamic batching disabled because it has to draw GameObjects twice.

When you use Generic, using root motion is more expensive

• When you use Generic, using root motion
   is more expensive than not using it. If your animations don’t use root motion, make sure that you have not specified a root bone.
