The
*WriterManpage*benchmarks have weird behavior. The number of allocations didn't change, and the performance numbers differ more than one would expect in this scenario.Even more perplexing the
*ReaderManpage*benchmarks exhibit performance differences, where nothing should have changed in the encoded output.
