Alternatives to C/C++

Instead of sticking with C/C++ for performance consider:
1.Free Pascal -Small memory use,very fast, easy debug
2.OCaml - medium memory use, fast,very terse, functional and secure.
3.FreeBasic - very fast,easy to use, low memory use, supports QBasic code as dialect. Other Basics to consider: PureBasic/Gambas/PowerBASIC
4.Digital Mars D- fast, easy to write and debug, large library, transition from C/C++ much easier.Garbage collection can be turned off.

I've read that malloc can take as long as automatic GC.
Are you are talking about the "GC can be as fast as stack allocation paper" from the 80s?
