    If you wanna know what your garbage collector is up to the best place to look is in the GC logs. This session will explore what information can be can read from the logs and what you can do to improve GC performance. GC logs are like any other ascii log file in that they can be full of 1000s of cryptic entries which make trying to figure out what the logs are saying without any tooling, a daunting task. In this session I will introduce tooling designed to help you make sense out of your log files. Some of what the tooling can tell you is if your JVM's heap is misconfigured as is the case for a large number of applications currently running in products systems. These application are starved for memory in at least one of their internal memory pools. But it’s not only starvation that can a cause of poor performance or long GC pauses. Too much memory can be equally as problematic. Or your problem could be as simple as your application calling System.gc(). Properly read, GC logs are key to solving all your Java heap rooted performance problems.

        Editor's note: You can see a transcript of this talk here: https://gist.github.com/1273387 Narihiro Nakamura is a research worker at Network Applied Communication Laboratory Ltd.. He is a CRuby committer. And he is a Garbage Collection lover. So, he works on GC in CRuby. Lazy Sweep GC is one of his works for CRuby's GC. You can use it since Ruby 1.9.3! Parallel worlds of CRuby's GC "CRuby adopts Mark Sweep GC Algorithm now. In my presentation, I talk about Parallel Mark Algorithm for CRuby's GC that improves Mark. Parallel mark divides a mark phase into a plurality of threads and it parallely execute. Recentlly, 8 core computers are not rare. In such an enviroment, GC will be speed up, if it distribute tasks to each core. I'll talk the parallel mark algorithm and implemention, result of benchmark."
