...ted the each write case to be incrementally unique, to prevent JIT... And honestly, unless the JIT optimization is that good (which I find it hard to believe), it could just be a case of poorly optimized read, or heavily optimized writes (write to immediate buffer?)... which is worth investigating :...

Flatten nested dictionaries, compressing keys
... is not likely an issue, but I'll elaborate on the second point in case anyone else cares: In implementing this, there are numerous dangerous choices. If you do this recursively and yield and re-yield, or anything equivalent which touches nodes more than once (which is quite easy to accidentally do)...
