This is great (and about time). Nice find! It's funny that they still include HTTPS Inspection in the table despite it no longer being offered as a public feature.
Also kinda curious that the MX68 is still only rated to 600Mbps.
I don't understand why they would update the chart just now as they are about to launch multi-threading on the MX250/MX450. The numbers should change again.
Yep, 600Mbps sounds conservative compared to what others have commented they can get.
I imagine this has been in the works for a few months already. Hopefully it gets updated more frequently now to include performance improvements (such as multi-threading).
