Thanks for trying it! I'm curious why it would be slower (perhaps less locality? perhaps the ...Id...

I think it's because statically allocated strings are not interned.
That would explain such a difference.
I think deepfreeze should stop using statically allocated strings for interned strings too.
… or consider the statically allocated strings the interned string value. Unless another one already exists, but that shouldn't be the case for CPython internal strings. Stefan
