FAQ

Q: Is this implementation faster than the original Sdust?

A: No, it's about 1.5 times slower. However, it becomes quite fast when multi-threading is enabled.

Q: Does this implementation consume less memory than the original Sdust?

A: No, it appears to consume about 5 times more memory. Enabling multi-threading further increases the consumption.

Q: Why was it created?

A: It was created to explore how much performance could be improved using Crystal, a language similar to Ruby.
