Comment #12 on issue 2097 by lemeslep: sha1 compiled with Emscripten runs
10X slower than with SpiderMonkey

@#8: I'm also facing serious speed issues with my 8-bit emulator on Chrome.
After investigation, I found that the culprit lies mainly in the CPU opcode
dispatcher. I've implemented it using some huge switches.
Those switches run much slower (between ~3 times to ~7 times slower!) on
Chrome compared to Firefox.
I've posted an issue about it here:
