If that's the case it would be great if the Ember team updated and optimized Ember and Glimmer on those benchmarks. A lot of people in the JS community use those to compare libraries and frameworks.
Definitely agreed. We’ve been focused on optimizing for end-to-end, realistic benchmarks. One of the Ember core team members, Kris Selden, has been working on a testing framework specifically for this actually: https://github.com/TracerBench/tracerbench
Now that we have a full set of new features, and are comfortable with the performance as a whole, I think we can also start to tune for some microbenchmarks. Our primary concern was to not over optimize for microbenchmarks at the expense of real world performance in real apps, which can happen if you’re not careful.
