OPTIMIZED EXECUTION OF DYNAMIC LANGUAGES

In one aspect, a method for optimizing executing of dynamic language code is provided, the method includes identifying a first dynamic language function call during runtime, the function call including argument values for one or more arguments of the function, calculating a type signature for the one or more argument values of the function, determining if a function associated with the type signature is stored in a cache, looking up the function in the cache when the function associated with the type signature is stored in the cache and dynamically calling the function associated with the type signature when the specialized function for the type signature is not stored in the cache.
