Of JavaScript AOT compilation performance

The fastest JavaScript production implementations use just-in-time (JIT) compilation and the vast majority of academic publications about dynamic languages published during last two decades focus on JIT compilation. This does not imply that static compilers (AoT) cannot be competitive; as comparatively little effort has been spent creating fast AoT compilers, a scientific comparison is lacking. paper presents design implementation an compiler, focusing performance analysis. reports experiments, one based standard benchmark suites new benchmarks chosen for their diversity styles, authors, sizes, provenance, coverage language. first experiment shows advantage to which expected after these have paid very tests. second more balanced results, compiler generates programs reach competitive speeds consume significantly less memory. evaluates techniques we either invented or adapted from other systems, improve
