Which, if I'm not mistaken, is what you had... However, when something "fits in the cache", the speed can be up to 4-8x faster; thus your compiled program probably fits, or almost fits, and seems faster. The FB compiler is too large to fit, on a 7200/80. (It fits in the 1Mb cache on a G3... :-) Bill
