I have an ERLite-3. I've had it about 6 months. Originally I got it to combat the "bufferbloat" issue which comes from having a large family with many devices.
We have 100/20 business internet service, but as I'm now well aware, you can't use the smart queue features (or any kind of queue features) to rate limit a 100 mbit connection with an ERLite-3. If I add a queue limited at 80mbit, the performance actually drops to 40mbit. The device simply can't keep up.
My question to the smart people here is: where is this limitation spelled out in the product datasheets? I am looking at ordering an ER-4, but I don't know how to confirm this will actually work with my internet connection. What if I upgrade to a 200mbit account? How can I know which product will actually be able to handle my internet connection? I didn't think that it would be that much of a problem for dedicated devices like this.

Thanks for your time!

It isn't in the datasheet. The EdgeOS manual has some max BW QoS figures, but they're quite optimistic .
Also, on Cisco, this data is also not spelled out in datasheet (at least on gen1 routers like 1841)

hi i have an EdgeRouter Pro and its limit is about 300 Mbps Total Throughput so 150/150
but the ER-4 as the same clockspeed with double the cores so i would expect at least a 250/250
i might be wrong tho ...
