My understanding of this is the ReadE basically generates the same code as a Chain. Chain is a random I/O operator and will not allow record blocking to occur. There's a compiler info message about record blocking that disappears when you use ReadE on a file.

I can understand that there would be a small performance hit with the ReadE (< 5%) over Read but >10% just seems wrong.

WOW. I am absolutely floored. With a single-field key, READ/compare is about 10% faster than READE. Who'd'a thunk?
