I ran the test with a payload of 32 bytes. Here are the results:
Non-Contented test:
* ptmalloc: alloc 39M/s, free 49M/s
* tcmalloc: alloc 42M/s, free 40M/s
* jemalloc: alloc 21M/s, free 21M/s
* t_stack: alloc 110M/s
Contended test:
* ptmalloc: alloc 6.1M/s, free 6.4M/s
* tcmalloc: alloc 25M/s, free 11M/s
* jemalloc: alloc 18M/s, free 6.5M/s
Note that the results are less accurate that those provided in the article since the number of allocations per batch is smaller (due to the limited amount of RAM available on my desktop).
That's said, the article does not pretend benching realistic patterns.
