Hi to every body and excuse for my english...
I have one question for you.
To mesure the redution of trasmissive rate (Mbits/sec) consequence to
enabling of IPSEC I had used 2 benchmarks: PCATTCP and IPERF.
Using PCATTCP I had recognize a reduction of trasmitting rate igual to
33 %.
Using IPERF I had recognize a reduction of trasmitting rate igual to
25%.

Why? Are different the operation that these benchmark execute?!

Thank you...
