Computer app.
The CPU has 3 hardware threads available to the application.
Unity uses at least 2 (main and rendering), so creating more than one additional worker thread from managed  code is not likely to yield any additional benefit.
But this of course depends on how the application itself is behaving. For example, a GPU-limited application might have plenty of CPU time to spare.

* The numbers above are theoretical limits. It's good practice to allow for a few MB of unused buffer space, to not run out of memory while running the application.
 
* The memory listed as "Available to App" is used not only for scripts, but also for any kind of additional game data, such as meshes, physics/collision structures, etc.

Unity for PSM reuses the same graphics driver used in the "Unity PS Vita" <br />
This ensures that a high-performance rendering path is available also with Unity for PSM.<br />
But the graphics driver behaves quite differently in one key aspect : A shader instance is only compiled when it's actually used, i.e. right before rendering the material from which it is referenced.


This means that the classic fallback shader mechanism provided in Unity is not available on PSM. <br />
Unity for PSM reuses the same graphics driver used in the "Unity PS Vita"
An unsupported shader (a shader with a programming error, or otherwise fails to compile) will simply be replaced with the Default Shader,  which usually produce a pink color output (and the compilation error output written to the device log).
This ensures that a high-performance rendering path is available also with Unity for PSM.
Because this step can sometimes be computationally intensive, shaders already compiled are cached, and can be reused on subsequent application runs (provided the shader hasn't changed). One benefit of compiling shaders at runtime is that Unity for PSM also supports the older Unity "fixed function" shaders.
