FAST_IPSEC vs IPSEC performanc

[Michael Vince]

Hey all.

I have been googling around the Internet for information about IPSEC and 
FAST_IPSEC for freebsd on the Internet and wondered what gives best 
performance
when I came across this  http://people.freebsd.org/~pjd/netperf/
It has some nice graphs / figures on performance of IPSEC and FAST_IPSEC 
via gigabit ethernet devices and as long as I am seeing this correctly 
it appears the regular IP_SEC is a fair bit faster in some areas then 
FAST_IPSEC.
Does any one know if  this information correct?
Anyone done there own benchmarks?

Thanks
