>> DrRacket's GUI is more responsive. Eli, Matt and Robby,
Qualitative comments: I don't know if change occurred in v5.3.1 or v5.3.2 but DrRacket GUI is now materially more responsive when editing large racket source code files (~2500 lines). I thank you very much for the improvement. I recompiled all my source code under 5.3.2 after midnight and have been running same in background. No issues to report. Same to slightly faster (5%-ish)performance relative to v5.3.1. Major garbage collection cycles seem very fast in both versions. I don't have hard data to share, but I think I'm now observing that minor garbage collection cycles seem to take longer than the major cycles. (is that even possible?)
