I didn't have time to try another iOS. We had 3 peers with 100mb connection to each. We couldn't get the router to process any connection beyond about 10mb. It was terrible. We were also terminating 300 IPSec tunnels, with Zbf and IPS running. How much can one router bear? You want the router to be able to perform multiple functions, the full routing table seemed to put a lot of load on ours.
