Not sure what the point of this is. Microsoft never argued that Edge is faster than Chrome at everything. They specifically said it was faster for certain benchmarks.

But the author is upset because it isn't faster for the specific benchmarks he prefers. If it's slower at Peacekeeper does that specifically mean that the browser is now slow ?

And then weirdly Mint/Linux comes into the argument as though it has any relevance to Edge. Nobody is switching operating systems because of browser microbenchmarks.
