This might be a wild guess, but are you using typed/racket as the language? On
my machine (Windows 7, DrRacket 6.6), if I use #lang typed/racket, evaluate it
than type "Hello World" in the REPL, it takes about 2 seconds to display the
result (after that it seems to run fast). If I just use
Okay, thanks. (For the record, I use Mac OS X 10.11 routinely and do
not experience this issue, so there must be something something else
going on. I'm not sure what guess to make next, but it is interesting
that 6.2.1 didn't have this issue.)

Can you try opening a Terminal window and Running the command: (quit
DrRacket first and you should be able to just paste that command into
the Terminal window and hit return)

This should print
Matthias, hello! Thank you for your reply.
I downloaded dmg. Then I copied DrRacket folder into Applications folder and
start DrRacket without any additional tuning.

This sounds like your interpreting code instead of running compiled code.

To reproduce:
1. Download DrRacket x86_64 v6.5 [1]
2. Start on OS X El Capitan.
3. Type in "hello world" and press run...
It takes about 2-3 seconds to execute this code on my machine. Also "flawed"

Ask Ryan to expose the backtrack continuation. Then accumulate
the anti-effects and attach them to the backtrack continuation.
If it is thrown, it’ll automatically undo the effects.

For my current use-case, using the racket in module mode, with the right #lang
directive at the top of the .rkt file is enough.
For the interactive mode, however, I was expecting something like
racket -I 'constructor-style-print
One option is to use Alex Knauth's package quote-bad.

If you want to see how he sets the print handler:
Hi,
I'd like to use the Constructor printing style in the command-line REPL, so
that it behaves the same as in my current DrRacket config, e.g.
> (list 1 2 3)
(list 1 2 3)
Using https://docs.racket-lang.org/reference/printing.html, I've been trying to
set (interactively) the right parameters
