[OpenSIPS-Devel] [NEW] Improved version of f_malloc

[andrei dragus]

Hello,

A new version of f_malloc (fast memory allocator) was added to the trunk.

Improvements over existing f_malloc implementation:

    1. No more memory fragmentation:
       - Memory fragmentation is prevented during normal allocations.
       - If an allocation cannot find a large enough size, it will start a forced memory defragmentation until it builds a proper size. ( this may be a little slow, but it will generaly not get to this case because of the prevention methods).

   2. Allocation speeds have improved*:
      - old version: malloc = 0.075 ms free = 0.037 ms
      - new version: malloc = 0.050 ms free = 0.043 ms 
  
Hope you find this useful.

Thanks,
Andrei.
