 One simple thing to check would be whether the slower machine has less available memory, and the program is spending a lot of time swapping. For example, you can use the "top" command and look at hypermail's size and %mem while it is running.

 If that doesn't explain the difference, it will probably be hard to figure out. You could try looking at the file creation dates to determine whether the slowdown is spread evenly between each file creation or whether creating one particular file is slower. Or you might try doing a "man gprof" for info about how to profile the execution times of a C program.
