I have not investigated closely, but Racket CS might perform more function inlining than plain Chez Scheme. That's because Racket CS performs it own inlining pass to better support cross-module optimization, and then it hands over the result to Chez Scheme, which performs its usual inlining. Another possibility is that Racket CS changes evaluation order for some function-call expression by forcing left-to-right evaluation of the arguments. That is, Racket CS might force an order of evaluation that just happens to be slightly better. Along similar lines, the differences are small enough that it could be just from accidents of allocation order and size that trigger a memory-alignment pattern that happens to be slightly better for some layer of caching. -- You received this message because you are subscribed to the Google Groups "Racket Users" group.

Re: [racket-users] updated Racket-on-Chez status
Thank you for all the hard work you've put into this, everyone. The benchmark graphs are impressive! One thing that surprised me is that there are a handful of tests (tak1, dynamic2, tak, mazefun, maze2, collatz-q, collatz) where Racket/CS actually outperformed CS. How is that possible?

Just wanted to say thank you for the update and for the honest report. I look forward to using Racket CS, and to seeing how easily new features can be incorporated :) On Tue, Jan 29, 2019 at 2:49 PM Matthew Flatt wrote: > Here's a new status report on Racket CS: > > http://blog.racket-lang.org/2019/01/racket-on-chez-status.html > > Short version: Racket CS is done in a useful sense, but we'll wait > until it gets better before making it the default Racket > implementation. > > > Matthew > > -- > You received this message because you are subscribed to the Google Groups > "Racket Users" group. > To unsubscribe from this group and stop receiving emails from it, send an > email to racket-users+unsubscr...@googlegroups.com. > For more options, visit https://groups.google.com/d/optout. > -- You received this message because you are subscribed to the Google Groups "Racket Users" group.

[racket-users] updated Racket-on-Chez status
Here's a new status report on Racket CS: http://blog.racket-lang.org/2019/01/racket-on-chez-status.html Short version: Racket CS is done in a useful sense, but we'll wait until it gets better before making it the default Racket implementation.
