Hmmm. I did some additional experiments using the JRockit JVM on Windows XP, and JRockit not only has equivalent memory usage for Clojure 1.2 and 1.3 alpha1, but it can also run these programs with significantly less memory than HotSpot. HotSpot is similar, but not identical, in its memor

While updating the benchmark programs I wrote for the shootout web site for 1.3 alpha1, I came across a program that required much more memory to complete in 1.3 than it did in 1.2. I boiled it down to a simpler program that has similar properties.
