Hmm, unless I'm misunderstanding, in the thread linked in the wiki above, it says the ER-X can handle gigabit reasonably:
- SQM works with software flow offload, allowing throughput of up to 200mbps with +3ms bufferbloat. Any thing faster maxes the CPU.
- HW flow offload resulting in 900mbps but the +200ms bufferbloat hurts
- NO HW flow offload, NO SQM, resulting in 550+ mbps with +80ms bufferbloat
So if it's using hardware offload, it can do 900Mbps with a 200ms latency overhead (when the link is saturated I assume?). If that's correct, then it sounds fine to me.
