I built a runtime comparison of npm and yarn a while ago. It builds the same two things every day with different configurations (cold cache, installed, package-lock file)

The data can be seen here: https://docs.google.com/spreadsheets/d/1ZE5B4qJw1kNGMzjgslcW...

Am I reading something wrong or is the comparison really indicating that yarn is several times slower than npm?

The general conclusion and our experience has been the opposite and one of the big reasons why yarn exists.

Do those graphs show time in seconds? If so, I'm shocked by how slow yarn is...
