It certainly is another option, I’ll re-run the tests with it and post the results

What if using a HashSet?

@nouseforaname: You are right about FastArrayList being targeted for multi-threaded environments, I’ve removed it from the test since it doesn’t contribute to the point I tried to make.

Regarding fast mode, it doesn’t make a difference if you use the class from a single thread (like we are in a straight loop).

thanks for the feedback!

You’ve missed to put FastArrayList into fast mode after inserting! Read the documentation for more information.

Also, the FastArrayList implementation is used in multithreaded environments.
