Not OP, but AFAIK one big issue with FIL-C it does the checks at runtime, adding overhead, don't quote me on this, but IIRC is around 20% slower.

2x slower and 4x less memory efficient were the numbers I heard a year or so ago. Reaching within 20% of full native performance while using a garbage collector sounds too good to be true.

Do you have any actual benchmarks?
