Standard Interpretation Optimization

tip

Standard interpretation optimization technology is only available in the commercial version.

The standard interpretation optimization greatly improves the performance of interpreted execution using a variety of techniques, benefiting basic instructions (such as variable access and numerical calculations) immensely.

For example, in numerical calculation instructions, the performance has seen a qualitative leap after using standard interpretation optimization technology, with an increase of 280%-735%! Special codes like typeof instructions have seen an increase of over 1000%.

Implementation​

The standard interpretation optimization uses the following techniques to enhance interpretation performance.

  • Instruction dispatch optimization
  • Instruction merging
  • Useless instruction elimination
  • Special instinct instructions

Enabling and Disabling Standard Instruction Optimization​

Standard optimization is enabled by default. This setting is global and applies to all assemblies, including supplementary metadata assemblies.

You can manually enable or disable this feature using the RuntimeApi.EnableTransformOptimization function.


    /// Disable standard instruction optimization
    void DisableCodeOptimization()
    {
        RuntimeApi.EnableTransformOptimization(false);
    }
