In my view, there is enough information to deduce, with a high level of 
certainty, that single-threaded compilation performance (in general) is far 
too slow in chrome, and that this is a problem, irrespective of how fast or 
slow it happens to be in any other browser.

If there's additional insight to be gained from comparing single-threaded 
wasm compilation performance between any two browsers, I think that 
comparison can be made by any interested party, independently.
