I was playing with this library and found i could get significant performance improvements by changing the object classes to structs. There were a few code changes to correct breaking changes but i found a 50% speed increase in most use cases.

That sounds great, would you be willing to share a pull request? I'd be happy to use it even if it doesn't get accepted.
