Interesting, how do you derive at "4-10x slower"?

Running the exported notebook here takes

time py3 python.py real 0m0.145s

chrome: load html: 2sec run html: 13sec!

That's not 10 times slower, but a 100 times slower!

Still good start.

I have used Weblas "GPU Powered BLAS for Browsers" for matrix multiply and it smokes! https://github.com/waylonflinn/weblas
