Copy code

January 2021
We've compiled about one million lines of code (LoC) in our tests. Frontend performance is about 14,000 LoC per second while the overall performance of frontend and backend is about 5,000 LoC per second. These performance results are around 4 times faster than results of the existing compiler.

Unfortunately it’s 2x better. The frontend is 4x better.

(see last comment). Still a great improvement.

And I guess it means, optimising the backend could yield big improvements

@mikehearn doesn't that 4x frontend performance help for IDEs (auto completion, analysis etc) ?
