I'll take the dissenting view here. We often criticize people for putting too much emphasis on fake benchmarks and ignoring real world performance data. Here we have somebody actually testing the same thing he's going to be using (maybe). A few other tests may provide a insight into the problem, but at the end of the day, they aren't going to determine whether the ipsec link is usable or not. > Also if you're testing from the router itself note that results > when testing from another machine which connects through the router > are likely to be very different. This is very true.
