Since I installed 5.3.1 -- I'm currently on 5.3.1.5 -- DrRacket gets slower with use. It's snappy enough when first started, but after a while, it gets sluggish. Switching tabs (and I have only three open) takes two to three seconds, and scrolling pauses frequently. The garbage collector seems to be getting quite a workout. (I'm not using a memory limit, and my machine has about 3.5GB of RAM free.) Disabling online compilation doesn't fix the problem.
I just noticed that scrolling a buffer brings DrRacket's CPU usage up to 100%. I don't know if that's common or not; I've never checked before. I saw Robby's post on the PLT blog [http://blog.racket-lang.org/2012/11/drracket-now-more-responsive_15.html]. Are the changes described there in 5.3.1.5? -Jon ____________________ Racket Users list: http://lists.racket-lang.org/users
