IKEv2 offers a number of performance
improvements over the original version, including shorter negotiation
times due to a reduction in number of messages and additional
integrity verifications. Interconnection of a Cellular Base Station in India to a
Base Station Controller in the United States over a broadband internet
based connection required increased buffering to accommodate the
variations in round trip packet delay and the packet loss feedback
loop.

In a series of lab tests conducted under strict methodology to reproduce
real-life traffic (detailed test report available upon request), the IMP O650
confirms world-leading performance.
When used as a complete Email Security Appliance, with both protocol
filtering and content filtering (antispam and antivirus) enabled, the O650
achieves 3.1 million email per hour or 150 Mb/s of equivalent
throughput for 66 KB email, while providing best in class filtering.
Tests also show that when the O650 is used as a line of defence MTA, with
full protocol filtering (ie: Bizanga reputation network, RBLs, protocol
compliance, sender and recipient verification, format check) enabled, it can
sustain a load of 4 million emails per hour or an equivalent of 88 Mb/s of
throughput for 10 KB emails, and 1.7 million emails per hour for 65 KB email,
or 242 Mb/s of equivalent throughput , while achieving in excess of 40% of
