Re: [racket-users] Reducing Program Startup Time
Ok, those tests aren't particularly illumating (at least they were easy!) Is your Racket distribution on a local drive? Network performance can make a big difference. We've also found that the minimal Racket distribution can be quite a bit quicker when pulling in packages outside the main collects directory there's racket code that enumerates files and the main distribution installs thousands of files you may not need. Even local SSD file systems have a noticeable lag doing that.

Re: [racket-users] Reducing Program Startup Time
Are you sure you have up to date .zo files for all your .rkt files? How's the timing if you add '-c' to your Racket commandline? How about '-j'?

Re: [racket-users] Reducing Program Startup Time
Dupéron Georges I did what you suggested and placed a displayln at the beginning. There's a wait time between when I execute the program and then everything happens all at once - the displayln occurs at the same time as when the GUI spawns. > On Sunday, December 4, 2016 at 10:05:23 AM UTC-8, Matthias Felleisen wrote: > > Also consider lazy require.

[racket-users] Reducing Program Startup Time
I have a GUI program (located here, for reference: https://github.com/lehitoskin/ivy.git ) I'm working on and I've found that the time it takes to go from clicking on the binary (or calling from CLI) to getting a fully loaded window takes about 2.5 ~ 3 seconds. What I would like is to get it down to 1 ~ 1.5 seconds. Now, I've done some more obvious things like using racket/base and racket/gui/base and calling require on every specific package I use, but it seems that isn't enough to get the startup times where I want them. Are there any other obvious or generalized steps I could do that might help? Perhaps moving some code into expansion instead of runtime (not exactly sure what or how to do that, though)? -- You received this message because you are subscribed to the Google Groups "Racket Users" group.
