I am seeing severe increase in latency when in nstreme mode.
On an 54km link (but also on 2-3km links!) I see strange behavior - when in normal mode the ping RTT is 1-2ms (at that time link carries approx 1mbit traffic). When in nstreme mode, RTT varies from 8 to 60ms .. rarely 1-3 ms.
Shouldn't the 'nstreme 'controlled' mode be more consistent on the timing?
I also fail to see the behavior John said should be expected - interfaces in nstreme mode still lose packets (or at least give ping timeouts) fhen pinging the neighbor router.
