>Sure, it's possible to write a Java allocator/GC that will yield similar performance to the C++ code,

Didnt you just agree with me that it is dependent on the impl/end product?

Because what would be the reasons in isa world to make it not desirable

>The syntax of the language has constrained the implementation so that Java will practically always be slower.

The most interesting question is: by how much?

1% 3%? 30?

Java code is generally 2x slower than C++ code, unless you're operating entirely on primitive types. The JIT usually can't remove enough of the gratuitous memory accesses the language forces.

Youre talking about java end to end, we are talking about just syntax.

No. I'm saying that it may be theoretically possible to tune performance in some cases, but not practical.
