WebThe bench program measures the throughput of parsing and serialization for the a set of JSON representing typical workloads. These implementations are evaluated: Table 1.10. Implementations Methodology The input files are all loaded first. Then each configuration is run for a sufficient number of trials to last at least 5 seconds. WebParses the input using an instance of CrtAllocator, which uses the standard C++ allocator, and is designed for general use including mutation of the document after it is parsed. The Document object holding temporary memory is not reused between trials, otherwise memory consumption grows without bounds and invalidates the benchmark.

"WebMost memory allocations on the heap don't even happen in C or C++. Short lived objects exist on the stack and swapping your allocator with a different one won't change that. That most allocations happen on the stack doesn't change the fact that most malloc implementations are still heavily optimized for the fast path. " - Memory allocator benchmark
