@zwoop can you post the performance numbers of having a proxy allocator for the HttpSM vs not? |

I've tried this on master, 9.1.x and 9.0.x branches, and on the 9.0.x branch, it will assert always. 9.1.x or master does not have this problem, I think something changed around either the class allocators or the constructor / destructors for the HttpSM. |

The performance increase is not tremendous, about 5%. It's possible it make more of a difference on other hardware platforms, where the costs of the atomic operations on the class allocator causes more contention. |
