I'm seeing almost 2GB memory use for current Racket during the `raco exe` step and 5GB with Racket CS. Neither of those numbers seems reasonable, and I'll investigate more. > * Build time for my application, "raco make", is 98 seconds for > Racket 7.1 and 187 seconds for Racket CS That's expected, at least. Compile times are that much longer in Racket CS, generating machine code instead of bytecode. > * `df-test`, a test that runs mostly Racket code, has increased from > approximatly 5 seconds in Racket 7.1 to about 14 seconds in Racket CS. Much of the difference here is load time. On my machine, it's 5 seconds versus 10 seconds, where just loading "test/df-test.rkt" takes 3 seconds versus 7 seconds. Also, I think the loading effect is worse on Windows, for reasons that I haven't yet tracked down. Like compile time, load time has been a stubborn problem, but I'm optimistic that we can improve load time. > * the remaining tests, `db-test`, `trends-test` `aggregate-test` and > `fit-test` all have running times that are about 50% larger in > Racket CS when compared to Racket 7.1.

I tried "db-test.rkt", where it's 15 versus 25 to run and 5 versus 9 to just load. I'm not immediately sure why running is slower, but my initial guess is that the FFI adapter in Racket CS needs work. > Is Racket-on-Chez built in debug mode?

Thanks for the report! There's plenty here for me to investigate. Matthew -- You received this message because you are subscribed to the Google Groups "Racket Users" group.
