Is that correct?
Expansion in Racket v7 takes 1.5x-2x as long as the old expander. There's some improvement over the times that I reported before in http://blog.racket-lang.org/2018/01/racket-on-chez-status.html For example, `racket -cl racket/base` now takes under 3 seconds instead of 3.4 seconds, and `racket -cl racket` takes about 32 seconds instead of 38. But the new expander runs at about the same speed in both Racket v7 and Racket-on-Chez. It's possible that the expander will eventually run faster in Racket-on-Chez, but it's equally possible that we'll find ways to make it run faster on both. -- You received this message because you are subscribed to the Google Groups "Racket Users" group.
