My scenario: High end 64 bit computer (Win 7 64 gig ram Intel 4 core etc etc) and I have 629 clippers and 152,710 Clippees.
If I do a CLIP within ArcGIS - the process takes under 2 mins.
Attempting to do the same process within FME 64bit - using either the identical geodatabase OR even data saved as FFS - with the transformer set to Clippers first - had not completed the Clipping after 4 hours. I let a workbench run and it achieved a similar calculation after 7 Hours...
I've even noticed a similar time difference with Mapinfo -- Mins for clipping data versus hours in FME.
I've read posts -and tried things like AREAONAREA calcs after finding all from spatialfilter - But still slow....
I use FME so regularly that i'd love this to be rectified. We suspect that its the difference between trying to handle all the clippers at once, and dealing with them 1 at a time... Its such a vast order of magnitude difference in time - Wondering if their are any other suggestions from SAFE?
