It is polite to point out
where in the article you found that figure. On page 6, the author states:
Sun�s JVM allowed the applet to allocate up to 60% of
the physical memory, but not more.
Software-injected anywhere-in-physical-memory faults:
We were able to allocate N = 61,181 objects on
a machine with 128 MB RAM. . .
(emphisis mine)
Since the JVM by default has a default maximum heap size of 64Mb (
java command documentation), the 60% figure is just about right.
