I wouldn't mind porting this to Mac and Linux for you. You said you could help out anyone with that who'd be interested in doing so. PM me and hopefully I can get some binaries built for you to publish.
Performance issues and crashes were expected. Thank you for trying.
Though there is a way to speed it up, there's some weird behaviour when using the extension in the IDE when it's in multithreaded mode, so I turned it off. Turning on multithreaded mode makes it much much faster, but then you can't test your program in the IDE for some reason. I don't know what's going on with it.
