Theoretically, that's not true.
Good just-in-timing run core can run virtual machine code at almost the same
speed as native code. And a good garbage-collector is faster than malloc/free
(it pays some cost for surviving object, but for many short-lived objects, it
is a lot faster) and compacts the working set, which improves cache
performance. And these days, memory access cost as much as tens of
instructions, so cache performance can make huge difference.
Of course the cost of using garbage collector is bigger memory consumption,
because the objects are not recycled immediately.
