Paul, Nop... All packets are handled in HW assuming your actions are supported... Performance should be the same as regular routing as long as it's done in HW and you do not exceed TCAM resources.
In some older IOS versions there were issues with what happens when the next hop is not available... Packets were punted to the RP. This is not the case after SRD (I think).

I gather that the first packet is handled in software and from that point on the route exists in the cef table. Is that a big performance hit? What sort of throughput/number of connections can I expect to be able to handle before everything comes crashing to its knees? Do Cisco have any figures on this hidden away anywhere?
