If you write a new algorithm on DRLVM you can still compare it to the existing J9 algorithm :-) or the DRLVM algorithms. We are aiming to improve the DRLVM in this project, as mentioned elsewhere, J9 is not open source so no opportunity for you to contribute directly there. > Question: what algrithms you use to implement the garbage collection in DRLVM? > what compaction algorithm you use? Did you look at the website already? There are a number of documents that will be of interest to you, including a How-To for new GC algorithms [1] I suggest you check your ability to contribute to the project, then describe your ideas and work with Xiao-Feng and everyone on this list to implement it. I'm sure you'll get some useful feedback. [1] http://harmony.apache.org/subcomponents/drlvm/gc-howto.html Regards, Tim
