For what it&#x27;s worth, in my tests, Hoard (<a href="http:&#x2F;&#x2F;www.hoard.org" rel="nofollow">http:&#x2F;&#x2F;www.hoard.org</a>, <a href="https:&#x2F;&#x2F;github.com&#x2F;emeryberger&#x2F;Hoard" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;emeryberger&#x2F;Hoard</a>) significantly outperformed SuperMalloc on a machine without TSX. For example, on a simple microbenchmark that tests scalability, Hoard is 2x faster with one thread, and the gap widens with more threads (Hoard is 3.3x faster with 8 threads, 4x faster with 16 threads).
