Good benchmarks for testing GC performance/scalability

If you have access to SPEC benchmarks,  SPECjbb2012 and SPECjvm2008 are worth trying too. They're all multithreaded and in many instances would benefit from memory placement opts.

And I want to test the performance on NUMA multo-core server with some multi-threaded benchmarks with multi-GB heap requirements. I have tried DaCapo but its heap requirements are pretty small. I know of SPECjbb2055, but nothing other than that. Can someone please suggest me some benchmarks for this purpose.
