Tcmalloc

Tcmalloc (Chrome Allocator)¶

• Used in chrome's linux version as of December 2015
• Used in glibc 2.26+
• Uses tcache to store freed blocks
  • Stores the freed blocks per thread.
  • Uses singly linked lists in the fd of the chunk

TODO:

Differences:
- Thread local storage caching
- Singly linked list in chunk's fd (sim. to FastBins)
- All sizes
- Major performance enhancement
- Not even trying to be secured :/
