Hi,

for the GC vs no-GC ongoing discussions, I think this is a very interesting talk about one of the best GC implementations for Java VMs.

He doesn't discuss the cost of his system as well as not digging
into the details. Some good numbers, but lack of meat.

Yeah, I posted the link when I started to see the video, so I found out the same thing.

But it is common from Azul to do so, they won't disclose their VM secret sauce, otherwise they would put themselves out of business.

We do have a fairly rigorous paper that was delivered at ISMM in
2011 that describes the C4 garbage collector, for those
interested. Link is http://www.azulsystems.com/resources/wp/c4

Thank you, we are interested. D language has a very Java-like OOP, but for most D code the allocation patterns are different from Java apps. In D structs (and arrays allocated in place) are common, so quite less garbage is produced. And while the D specs are designed to allow a moving GC, in practice there's also the need for some pinned down objects, as in C#, for access to C libs.

Hopefully we'll have a wonderful GC for the D language ;-)

Many thanks for providing the information.

Sorry about the remark.
