Yes, and I am still exploring. It is possible I have some scaling issues in dictionary which are not about compiled or not but about the cost of mutating data in a dict and gc costs.

Things like key lookup are already well optimized. So finding a more efficient algorithm might yield easier performance gains.

If you have for loops inside for loops, that's one place to attack. dict iterators, etc.
