The strict mode benchmarks for Oj are in the test/perf_strict.rb. Others are are in perf_*.rb.
If callback parsing is not supported that's fine. Oj does support callback parsing as it allows elements in a JSON to be ignored. That save memory, GC, and performance. Your choice of course just as including callback parsers is a choice for Oj.
Ok, so you picked options that you knew would fail. Again you choice but there are certainly others that would trade a slight improvement in performance to not have 16+ significant digits. It's a choice. You are certainly entitled to you opinion but that doesn't mean everyone will share them.
I'm not sure what platform you are testing on but i'm sure there will be variations depending on the OS and the hardware. I tested on MacOS M1.
