WebAssembly (Wasm) has been relatively recently extended to support features such as garbage collection, references, exceptions, and tail calls that facilitate compilation of managed languages. In this paper, we capture a snapshot of the performance of these new capabilities. The first part of the paper presents a language-by-language performance comparison of six managed language implementations on Wasm to the performance to their native implementations. The second part of the paper focuses on the implementation of a single Scheme compiler and explores the impact of different choices for compiling specific aspects of the language. Our findings suggest that Wasm has become a promising compilation target for most managed languages but that its performance still falls short of that achieved by native code.
