I've seen a significant performance difference between the latest v0.2.2 and v0.2.1b.
For this particular cart, it runs significantly slower on the latest version when measured with a stop watch, but when using the stat(1), the system claims the opposite--i.e. that it's faster. (These are both being run from the .exe on Windows.)
I've included the cart for reference.
