Thanks Havard, those are some great improvements! I suggest that you also reach out to the user forum about this. Active SPIN users are most likely lurking there :)

Cheers,

Jeen

Hi,

I’ve been digging into the SPIN sail looking for easy optimisations. I’ve landed on the following and merged to develop:

 - 1.8x faster execution
 - 13.7x faster initialisation

This is achieved by skipping execution and validation during initialisation; and by switching from LinkedList to ArrayDeque in the SailSourceBranch for handling changes.

Would be great if those of you using SPIN in a project would care to test it out. It should also be available as part of the 3.0-SNAPSHOT nightly build on Monday.

Cheers,
Håvard
