That's really puzzling. It's almost like "make doc" is doing different things on our two systems: the build is somewhat faster on my system (ignoring "sys" time), but the doc build on yours is blazing. What chips does your system use? Are you using solid-state disks? And what release are you building? I'm not sure what the doc build does, but staring at 'top' output while it's underway shows lots of free memory, not a lot of CPU or disk activity. The doc build just proceeds ponderously.
