See below... Ugh. Got any hard numbers on the top speed of the edgerouter with shaping? At work we recently upgraded our link from 60/10 to 100/15 and the WNDR I have running the show can no longer keep up. I've been looking for a replacement and the edgerouter lite was looking like a possibility. I tried to use a TPLink AC1750 thinking that a newer setup with a faster cpu might be able to keep up. If I don't have shaping enabled it can do 200+ Mbit but with shaping it drops considerably. It's still faster than the WNDR but seems to max out at about 85 Mbit. -- Richard A.
