#4676 — About memory allocators..

Hello...

About memory allocators..

I think that mingw  uses MSVCRT memory allocator that scales well and 
that is better than jemalloc and better than hoard, please notice it 
here on the following benchmark:

https://github.com/andremussche/scalemm

But GCC on Linux uses ptmalloc2 memory allocator..

I have just took a look at the memory allocator  of the GCC C and C++ 
compiler on Linux 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 decent choice.

Please read this paper to notice it:

https://arxiv.org/pdf/1503.09006.pdf


I have used gcc mingw to compile my scalable counting networks that
use a lot the MSVCRT memory allocator, thus they are scalable,
so my scalable reference counting with efficient support of weak 
references does too scale very well, and my efficient Threadpool engines 
that scale very well do scale very well too.

You can download them from my website:

I correct: I mean microsoft MSVCRT memory allocator scales better than 
jeMalloc and better than hoard.
