Performance problems with DrRacket's editor

I am required to use DrRacket for a CS course I am taking and have run into the problem that the editing features of DrRacket are too slow to even be usable. The REPL window on the bottom works fine for the most part, but I can't write any code for my course.

I am currently running on an intel 2.2GHz x 2 with 5.7GiB RAM and Ubuntu 14.4. DrRacket it version 5.3.6.

In some cases, at least, the slowdown appears to be due to memory consumption. In those cases, saving your work, closing the program, and restarting is likely to help.

Although I don't recall what it was for 5.3.6, newer versions of Racket enable background expansion by default. It might help to disable this? To do so:

  1. Open the Preferences dialog.

  2. Click the Background expansion tab.

  3. Un-check the first check box, Enable background expansion.
