There was a performance bug in the runtime dynamic linker/loader
(rtld).  Most people never noticed because they're not running on
obsolete computers whose main memory is slower than some modern disk
drives ;-P  Doug fixed it when he noticed KDE was slow on a more modern
machine.

Anyway, use cvsup (or anoncvs, or whatever) & get the latest RELENG_4
(stable) sources.  Build & install /usr/src/libexec/rtld-elf.  Be
careful, messing up the rtld is a good way to end up with a mostly
unusable system -- make a backup of /usr/libexec/ld-elf.so.1.
