Background

I have two sites connected via 2600 series routers and a
point-to-point T1.  Recently we were able to "piggy-back" on a faster
connection using two Pix 515's and a VPN tunnel.  I'd like to keep the
T1 for load-balancing and fault-tolerance.  To do this, the clients
have to go to the router first, because if they go to the Pix and the
link is down, the Pix won't route the requests.  

Problem

The delay going from the client to the router and then to the Pix is
quite large, yielding a throughput of about 83% of that found when
going from the client to the router across the T1.  In contrast, going
from the client to the Pix directly yields a throughput of about 130%
over the router/T1 combo.

Question

Of course, there is latency involved in going up to the router first.
But is there a way to reduce the latency on the router and/or allow
the Pix to redirect the traffic in the event that the route is
unavailable?  I understand that the Pix doesn't do routing, so I'm
thinking that it isn't, but I'm looking for suggestions.
