I assume here that you're referring to MS Fortran. MS Fortran doesn't
use the SANE data types and trap calls, and as a result is about ten
times faster than any calls that use the SANE traps. The way to get some
speed back is to use doubles as much as possible, but given your memory
constraints you may be stuck.
