The best i've gotten between two RB 500's in a lab is 75 Mbit/s but that was using dual CM9s pr unit.
I'm sure someone has gotten more than that (i was just trying out a particular concept)
Care to share your configuration or concept on exactly how you achieved 75Mbps between two RB500's? NStreme2 or some other configuration using two cards? That sounds like it could be a record for a single RB500 series board.
According to my notes (these are lab conditions);
two cm9's using turbo (i didnt note frequencies)
tx power 4
nstreme dynamic framer-limit 2000 polling enabled
fixed at 54 mbit
absolutly all irrelevant services disabled (even the occassionally useful ones)
bonding on both interfaces, ( round robin ??? )
not using bridge
cpu @ 330mhz
one side had 2 cards in 'bridge' (wds = static ) mode and the other had 2 cards in 'station-wds'
bandwidth tested between two lazy computers using mikrotik bandwidth tester.
unfortunately i didnt have the manners to write down burst
Move along. Nothing to see here.
