GC performance benchmarks

[Pressenna]

Hello together,

I am working on a custom GC implementation for OpenJDK
(http://www.sockali.net/openjdk/).
So far I have created synthetic benchmarks to evaluate the
characteristics of the GC.
These benchmarks now indicate a speedup of upto 3 times when multiple
mutators execute concurrently on my test system.

I was wondering if you guys can recommend me a decent benchmark suite
to further evaluate these number?
I am especially after benchmarks that create large object graphs that
need to be collected eventually.
