We are planing a FD link, we will probably use RSTP on the switch to do the FD with fail over to HD. The question is when using nstreme in an FD configuration (regardless if it is RSTP, Dual Nstreme, OSPF, etc) is the link latency any better then a HD link? and if so how much better?
Thanx
From what ive seen when operating in FD the latency seems to be more stable which if you think about it makes sence.
Even more stable with congested links.

Do you define “better” as lower or as more consistent?
When using nstreme, the latency is more consistent when there is decent traffic (regardless of whether it is one way or two way) than on an unused link.
If you want the lowest possible latency and the link is not under much load, in most cases it means turning off nstreme.
ps. you never replied to my second email in April
It is for a back bone so it will have at least a few Mbs all at any given time. I have typically seen 3-5ms (rb333+XR5) on one of our nstreme links which is pretty good. If this link were to use dual radios would the latency actually be reduced due to the uni directional nature of each link or would I still see 3-5ms ?..
Sorry about the missed reply please resend.
You forgot to mention the length of your link.
For a 15km P2P link, you can get <2 ms with two radios and OSPF.
But, does reducing the latency by 5ms going to make any difference? Is it worth the effort?
