Abstract: We present an analysis of the memory usage for six of the Java
programs in the SPECjvm98 benchmark suite. Most of the programs are
real-world applications with high demands on the memory system. For each
program, we measured as much low level data as possible, including age and
size distribution, type distribution, thread-local objects, and the
overhead of object alignment. Among other things, we found that
non-pointer data usually represents more than 50% of the allocated space
for instance objects, that Java objects are fairly small, and that a
large fraction of objects is never accessible outside the thread that
allocated it.
