Hello,
About GCC and ptmalloc2..
I have just took a look at the memory manager of the GCC C and C++
compiler that is called ptmalloc2, and on a UMA machine with four 10-
core 2GHz Intel Xeon E7-4850 processors supporting two
hardware threads per core, the benchmark of the following
paper shows that ptmalloc2 is "scaling" decently, so i think
that ptmalloc2 is a correct choice.
Please read this paper to notice it:

Thank you,
Amine Moulay Ramdane.
