It is hard to say because it depends upon a number of factors:
- your allocation, deallocation pattern
- the algorithm used in a specific allocator
- the relative timing of allocations
and so on.
In general, a special purpose allocator will always be "faster" than a
general purpose one. It may also be "more efficient" (less unused
space). However, in general, I find it better to avoid allocation /
deallocation in my applications - especially in real time and "not have
that problem". There are several ways to do that; ask if you need some
examples.
