Standard Interpretation Optimization

tip

Standard interpretation optimization technology is only available in commercial versions.

Standard interpretation optimization uses multiple techniques to significantly improve the performance of interpreted execution, with basic instructions (such as variable access and numerical calculations) benefiting greatly.

Taking numerical calculation instructions as an example, after using standard interpretation optimization technology, performance has made a qualitative leap, achieving 280%-735% of the original performance! The performance of some special codes such as typeof instructions has improved by more than 1000%.

Implementation​

Standard interpretation optimization uses the following techniques to improve interpretation performance:

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

Enabling and Disabling Standard Instruction Optimization​

Standard optimization is enabled by default. This is a global setting that affects all assemblies including supplemental metadata assemblies.

You can actively enable or disable this feature through the RuntimeApi.EnableTransformOptimization function.


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