i think you must return to ccr1072, usually newer platforms take months to optimize
plus
a new operating system version
plus
a new hardware architecture
plus
a new hardware offload using ASICs
because of all this concurrent aggravating factors we can expect this process to be even more difficult than ever and i have no doubt MikroTik is doing all its effort to achieve sucess but it will take time
i think we are seeing the starting point of a new era for MikroTik Routers, but we will not transit it without pain
just remember how much time it took ccr1036 form its starting point, then how much for ccr1072 to reach its current state of performance and stability
if your requeriments are at the edge of what MikroTik can do today i dont think you can rely on waiting to improve until you reach the limit again and again unless you are decided to suffer for own will
The performance of the CCR2116 for MPLS traffic is really disappointing. I guess that for the CCR2216 it must be even worse, considering the price of the device.
