Memory pool stats can be toggled at compile time. By default these are set to ON. To disable tracking the stats, pass `-DENABLE_MEMORY_POOL_STATS=OFF` to cmake during generation. Benchmarks when MemoryPoolStats disabled. | Benchmark name | Time | CPU | Iterations | |---|---:|---:|---:| | AllocateDeallocate<SystemAlloc>/size:4096/real_time/threads:1 | 56.5 ns | 56.5 ns |
