Ipsec Overhead

David Garcia Jr.
Does any one know how to accurately measure the overhead of IPSEC? I found this ( http://tsc.llwybr.org.uk/public/reports/SWANTIME/printable.html).  If you are using an RSA key of 2560 length, does the overhead increase?

    Hi David Garcia Jr., 

    What kind of overhead do you want to measure, time, size or bandwith ?

    The speed of an IPSEC Connection depends heavily on the Processor, the overhad increases using larger RSA keys but only during the connection establishing process, once the connection is up and running it makes no difference.

    hope that helps

    kind regards
