A fast mmap based C++ memory allocator
ccalloc is a fast mmap based memory allocator which overloads the default C++ new/delete operators. It is fully implemented in C++11 and pthreads. The allocation trategy is bucket allocation with no free lists and per thread independent allocation buckets. The performance is on par with ptmalloc in bulk small object allocations. Different from traditional allocators ccalloc passes through only clean zeroed memory to the application eliminating non-initialized data issues. Because ccalloc is not managing free lists it is much more stable and scales much better for multi-threaded applications. Long running single threaded applications are not well suited. For maximum performance you should at least use a dual core system. valgrind support is included.
To use ccalloc in your C++ applications simple drop the source files into your project and add them to your Makefile/project file.
The only tunable parameter is CC_MEM_PAGE_PREALLOC in Memory.cc. Set it to one for 1 for maximum security or to a greater number
for maximum performance.
