Good benchmarks for testing GC performance/scalability

[Lokesh Gidra]

Thanks for the info. BTW, is SPECjEnterprise any good for this purpose? What i could understand is that it needs multiple hosts for testing. I want to GC performance on a single instance of jvm.

Thanks

Just an FYI, SPECjbb2012 is still under development.  Release date is later this year.  Even though both benchmarks are named "JBB" they are vastly different and are not comparable.  They both test business logic, albeit in slightly different ways.   SPECjbb2012 has an SLA requirement that SPECjbb2005 doesn't and the code for SPECjbb2012 is written from the ground up and shares nothing with SPECjbb2005.

Actually i have tried SPECjvm2008 but even there benchmarks do not have large heap requirements.

Is it worth to make both SPECjbb2012 and SPECjbb2005 tests or the former one covers the later?

Thanks

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.

Hello,

I am making some NUMA related optimizations to the parallelScavenge GC. 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.

Thanks in advance.
