Abstract: Although
garbage collection frees programmers from the burden of manually freeing objects that
will no longer be used, and eliminates many common programming errors, it can come with
a significant performance penalty. This penalty can become particularly great when
memory is constrained. This thesis introduces two pieces of work to address this
problem. The first is Elephant Tracks, ... read morea tool that uses novel techniques to measure
memory properties of Java programs Elephant Tracks is novel in that it places object
death events more accurately than any existing tool, and is able to do so with out
modification to the underlying VM. The second is the Deferred Garbage collector. Built
based on observations from the Elephant Tracks traces, the Deferred Garbage Collector
reduces redundant work performed by the garbage collector In this thesis, we show that
the techniques used by the Deferred Collector can reduce garbage collector tracing
workload in some programs.
