Doloto

Doloto is a system that analyzes application workloads and automatically performs code splitting of existing large Web 2.0 applications. After being processed by Doloto, an application will initially transfer only the portion of code
necessary for application initialization. The rest of the application’s code is replaced by short stubs — their actual function code is transferred lazily in the background or, at the latest, on-demand on first execution. Since code download is interleaved with application execution, users can start interacting with the Web application much sooner, without waiting for the code that implements extra, unused features.
