performance comparison:

Note：

The numbers in the column are the performance ratios of the two runtime engines provided. Workloads matrix and gimli are measured by the execution time, and CoreMark is measured by its reported score. A/B denotes the execution_time_of_B/execution_time_of_A, or the score_of_A/score_of_B. For example, matrix 22.02 means that execution_time_of_wasm3/execution_time_of_wamr-aot is 22.02, CoreMakr 8.79 means score_of_wamr-aot/score_of_wasm3 is 8.79.
WAMR provides two interpreters - the fast version for advanced performance and and the classic version for smaller footprint respectively.
