1. Implementation of WASM Virtual Machine Module Compilation, Caching, and Instantiation

Compilation Functionality: Successfully implemented the compilation feature for the WASM virtual machine module, which can convert WASM code into executable machine code. This functionality lays the groundwork for subsequent module loading and execution.

Caching Mechanism: Developed a module caching mechanism that effectively stores compiled modules, reducing the time spent on repeated compilations and improving the system’s response speed. The caching strategy has been tested and maintains efficient performance across different scenarios.

Instantiation Management: Completed the management of isolated execution environments, ensuring that each instance of a WASM module runs in an independent environment, thereby preventing interference between different modules. This management mechanism enhances the system’s security and stability.

2. Optimization of WASM Virtual Machine Module Loading and Execution Performance

Loading Performance Optimization: Analyzed bottlenecks in the module loading process and optimized the loading algorithm, resulting in reduced loading times. The new algorithm demonstrated a 30% faster loading speed in tests compared to previous versions.

Execution Performance Improvement: Implemented several optimizations to the execution engine of the WASM module, including improvements to the execution path of the instruction set and memory management strategies. Performance testing showed a 25% increase in execution efficiency, significantly enhancing the overall operational efficiency of the system.
