Probably it is real, but you're right that doing this a bit mo
Do you see any change if you start DrRacket in Terminal with
env PLT_INCREMENTAL_GC=n /Applications/Racket\ v6.5/bin/drracket
? (That's assuming that Racket is installed as "Racket v6.5" in the
"Applications" folder.)
As of v6.4, DrRacket uses an incremental GC mode to reduce pauses while

Hello, Robby! Thank you for your reply.
I have done quoting out register-collecting-blit and the flashing gc icon
disappeared. But the feeling of slowness is still present, I afraid.
I am timing execution with cursor blinks: it blinks once or twice in DrRacket

Hi Ivan: here is another experiment to try. What happens if you follow
these steps:
- start DrRacket
- open "Language" menu's "Choose Language..." menu item
- select "The Racket Language" (click ok to close the dialog)
- select the "File" menu's "Open Require Path..." menu item
- type "fr/pr/frame
Here's another experiment to try:
1) start DrRacket from the command-line, like this:
$ env PLTDRBREAK=1 /Applications/Racket\ v6.5/bin/drracket
You should see a small new window appears with two buttons, "Break
Main Thread" and "Break All Threads".
Hit Run and wait about half of the time yo
Thanks. I'm not seeing anything out of the ordinary there. Rats.

Sorry for the redundancy in paste, it seems like all the results are the same
but I have copied all five outputs, for the sake of specification.

Alex, hello!
Thank you for your reply. No, we are just using Beginning Student Language in
HTDP course. Apart from my bug report, there are two other similar reports on
our forums. But I don't know how persistent the problem is. On the one side if
we are the only students that observe that lag,
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 #la
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

the Terminal window and hit return)
