Steps to reproduce the problem:
1. Open http://axum.graphics/EmscriptenTest/
2. Look at console output "Blobifying took.." line
3. Compare timing result of running asm.js function. On Chrome: "Blobifying took 86ms" versus Firefox Dev Edition (47.0a2 (2016-04-06)) "Blobifying took 7ms"

What is the expected behavior?
Would expect timing to be approximately similar, not order of magnitude slower.

What went wrong?
Performance of _Blobify function in http://axum.graphics/EmscriptenTest/Blob.js was 10x slower on Chrome versus Firefox, as measured with Date().getMilliseconds()

Did this work before? N/A
