Sorry, in today's world of high-end routers 250kpps doesn't qualify as
"plenty fast". Can your box do linerate Gigabit Ethernet with minimum
size packets, on several ports simultaneously?


I didn't say that a 250kpps box was a high-end box.
One reliable Mpps is not high-end either, but it can carry quite a lot
of Mbps. What is C or M price for a reliable full feed Mpps ?

"My" high-end boxes never manage to impress me with their pps
capability before I'm disapointed in their reliability.


I'll reply to myself before Steinar does =)

In my experience a datacenter pumping out 1Gbps is usually doing
200-250kpps in that direction. Considering this a box capable of
around 1Mbps is "plenty fast".

pps/$ would be pretty good if I could use those in real life...
