RE: 10Gbps IPS - what you need to know

["C-Info" <c-info () blaisnet com>]

The question I would also ask is was this complete capture or sampling of
the traffic?

Copied from the test report:  "The device ably supported over 11Gbps
of traffic with the larger HTTP response sizes (21KB) and lower
connections per second (5,000 CPS per Gigabit of traffic) found on
typical corporate networks".

It appears to be some calcualtion mistake!  It comes to around
820-830Mbps (21Kbytes * 5000 ), not 11Gbps throughput!

> I think you missed "5000 CPS per gigabit of traffic". Since it is 10G
box, I would assume that there was 50000 CPS in total which gives around
8.5Gbps. If you add usual overheads TCP header, IP header, Ethernet
header, the total throughput might go beyond 8.5Gbps.
