AIUI, GEM is or includes a process that applies a sigma filter. Running such a
filter over a large pixel-dimensioned image can be very
process-cycle-intensive, depending on the filter dimension parameters. It does
not seem surprising that it could take quite a while on a 400 mhz machine.
There's a brief description of a sigma filter at
