    Abstract: Aspects of the subject technology relate to a computer-implemented process, including steps for compiling a first method call at a first call site in code of an object-oriented language, wherein the first call site is associated with a first selector, referencing a global cache comprising a plurality of per-selector caches, wherein each of the per-selector caches is indexed based on a corresponding selector identification and identifying a first per-selector cache, from among the plurality of per-selector caches, using the first selector. In certain aspects, the process can further include steps for invoking a method on a first object by performing a lookup in the first per-selector cache using a class associated with the first object to determine if a first target function exists in the first per-selector cache. Systems and computer readable media are also provided.
