We experienced this problem also. I'm glad to have finally heard we
weren't the only ones! However, cisco has since found a fairly serious
memory managment bug related to bridge learned address table management,
which has this "slowness" problem in its list of observable
manifestations. Other problems observed were dead console ports, and
outright crashes. Since the bug is in learning table management, the
more churn there is in table management (the larger the number of
ethernet addresses to be managed), the more likely an individual router
appears to exhibit strange behavior.

Unfortunately, I do not believe the "fix" has made it into any
production releases yet. We have an interim release, which has proved
vastly more reliable than ANY previous release of cisco gateway code.
The bug affects both IGS and CSC/3 variants.
