Nick,
A secure tunnel interface is only as fast the entire network path end to
end. You can have a ST interface configured on a 100meg link but if the VPN
is over the internet and your internet connection is only 10meg...
If the secure tunnel (VPN tunnel) Isn't on your local lan and you're not
100% on the health of the entire network path end to end (or these are not
cabled back to back with a VPN tunnel running over them). I would take a
look at configuring juniper RPM over the IPSEC tunnel. That will tell you
the latency, jitter and packet loss over that VPN tunnel.
Additionally speeds will never be as good through a vpn tunnel as not. With
IPSEC comes additional over head and packets in many cases will need to be
fragmented or the MTU made smaller. This is just a draw back of using an
IPSEC VPN.
I hope this helps,
-Tim Eberhard
