The NM slot in the 3800s is connected to a PCI bus, so one would think that would be adquate to support your four 100 Mbps ports. However, it's possible the particular module your using might have limited bandwidth to how it interfaces to the module slot. I'm unable to find any mention on that detail. Unless someone else knows, this might require information from Cisco.
Have you tried a throughput test between ports on the NM-16ESW? If not, you might try both L2 and L3 and see if there's any difference. In the former, traffic should stay within the switch module. With the latter, it would need to jump VLANs defined to the router. If you see a major difference between the two, it might further document an NM interface bandwidth bottleneck.
Something else to check, the 3845 can run short of performance at high forwarding rates much, much sooner than most L3 switches. What's the CPU utilization look like during your tests?
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
