There is no such thing as "compilation speed". There are lots of different CPUs in existence: some specialized for mobile, some for home desktops, and some for multi-million-dollar super-computer compilers in the cloud.
So it's about time we start measuring compilation in terms of cost (given free market competition between different cloud service providers) rather than time. (There's also overhead time to sync your source code into RAM of the compiler in the cloud and return the result, but on the modern Internet that's less than 0.1 seconds.)
