Calm down. How about if *you* do a little more analysis and find out
where the slowdown occurs? Is it in the fscanf code? Is it simple
reading from the disk? Writing to the disk? Does it go away if you
stop using floats?
You can also use strace to find out where any slowdown occurs. Compare and
contrast it between the two versions.
