Re: 1921 vs 891 Throughput Testing ZBFW is zone based firewall, so yes its a firewall. 891 isnt necessarily optimized moreso than the 1921, but i am suprised how well it does. If the 891 had 2x1gb it could pretty much keep up with the 1921 with zbfw throughput
I used IPERF for the throughput testing. I did 3 streams for 60 seconds, so it adds up how much data each stream had in the 60 seconds for the total data transfered and total throughput which is the last line of each section starting with [SUM].
1921 3 streams, each stream did what was listed, comes up to 2.46Gbyte which comes out to 352mbit over 60 seconds.
891 3 streams, each stream did what aws listed, comes up to 670Mbytes which comes out to 93mbit over 60 seconds, obviously the 100mbit port is the limit here not cpu.
hope this helps clear things up
