What seems clear though is that Bun/Jarred really care about performance, since it's a big part of the tweeting/public communication. Maybe the tests are not the best from a real-world comparison, but the fact that he's constantly trying to make every small thing high performance would suggest that performance IS important for Bun. So people might disagree on "how much better", but I'd not be surprised at all if a system built from the ground up with a big focus on performance is faster than the competition.
