True. This is especially bad news if all the traffic is destined to a
corporate server, for example. You think you're sharing the load across the
two links, when actually you aren't. The router learns which interface to
use for the destination IP address of the server, puts this info in its
fast cache and continues to use that interface indefinitely.
On the other hand, if the traffic is going to a diverse set of IP
addresses, then the load sharing is more fair.

Turning fast switching off might not be a good idea, though, since the
packets-per-second for process switching is much slower. You would probably
go ahead and make this tradeoff if you saw that the
destination-by-destination load "balancing" was not creating any balance
whatsoever.
Also, you could look into CEF which is smarter about the load sharing.
