The performance difference is a small constant factor, perhaps 1.05x, perhaps 3x depending on the workload. If you are writing kernels, high performance graphics, signal processing, numeric analysis - sure, that's significant.

For the typical application though, it's fast enough, you get same order of magnitude performance as C++ or Rust with a almost Python like mental load. As the success of other dog-slow languages show, this is a major selling point.
