A ptp link with RB911

We have a ptp with rb411ah+rb800, single chain at 40 MHz, nstreme and WDS (but not for bridging). Max throughput is ~ 70 Mbps, with a cpu load on the 411ah about 60 %.

For 1 day, we used a rb911, ROS 5.25, single chain, nstreme and WDS. At 60 Mbps, packet loss was about 7 %.
Routing table isn’t so big: ~200 entries.

Overclock is viable, but is there a better way? Maybe MPLS? Or, simply, is rb911 not good for this ptp?
Bridging is less than a last resort, but if it is the only way, I’ll consider it.

Thanks

You can use RB711, but you have to use 2 chains. You can achive someting similiar to this:

Thanks.
Yes, dual chain is a must.
I see you’re using 6.5. Did you ever tried 5.x on that link?
