>Still, I actually tried PyPy on a string-based workload and it was slower than CPython and used more memory. I don't know why but that contributes to my feeling that JITs are bad for string-based workloads.

Now that I'm implementing a interpreter for a relational language and from what I know for why python is slow:

And also:

Is challenging to be dynamic and also fast. So, you need to design the language/runtime with performance in mind, or at least, to minimize what could be very slow (that is what I'm triying).
