[racket-users] Re: How do I debug this performance problem?

It turns out that a chaperone introduced at the typed-untyped boundary was causing a certain important function to run at least 20x slower. I've added prop:authentic to all my structs and am updating the code so that Typed Racket no longer tries to create chaperones. I've noticed that Typed

Re: [racket-users] Re: Executable file size and raco demod

I installed the latest build, and it does start. Generated executable is 80MB vs 32MB for 7.9 BC, about 10MB more than 8.0 release. I understand that there's a difference between bytecode and compiled binary size with CS, but I'm not certain if we're talking about the Racket distribution

Fantastic. Thanks for the info and the new build! Can’t wait to give it a test drive. Dex From: Matthew Flatt Sent: Monday, April 5, 2021 3:18:17 PM To: Dexter Lagan Cc: Racket Users Subject: Re: [racket-users] Re: Executable file size and raco demod The

Looks like it's the opposite. At the moment Utah's is half the size. I'll install the current Utah's and compare generated executables with 8.0 release. Utah: [image: Utah.png] Northwestern: [image: North.png] On Monday, April 5, 2021 at 11:42:46 AM UTC+2 Dexter Lagan wrote: > Hi Matthew, >

Hi Matthew, It is indeed the one from Utah. I’ll give the other one a try and report back. Thanks for looking into this! Dex On Sunday, April 4, 2021 at 8:32:00 PM UTC+2 Matthew Flatt wrote: > Hi Dex, > > Are you using a snapshot build from the Utah site --- as opposed to a > snapshot
