Adding to this great comment with my own experience at work where we extensively use signal processing and time series compression algorithms to visualize large amounts of biological signals in the browser.
WebAssembly is less than 10%-20% slower than native code in our benchmarks and tests for algorithms like fast wavelet transform and bit packing.
WA allows us to aggressively optimize ahead of time when compiling, and be less sensitive to JS engine performance pitfalls around JIT optimization and garbage collection.
