Brad, FM converts (on the fly) PDFs to EPS internally, so if you have a lot of them (I'm assuming one of your PatternStream catalogues) and you don't have your TEMP area on a big fast SSD, it's going to spend a lot of time writing out and reading back in temp files.
All I can suggest (though you don't want to hear it) is to create an Acrobat actionscript to batch convert the PDFs to EPS first and then try those in your automation. Perhaps do a small batch as a test to see if the throughput is improved. Regards, Arnis
