Apologies, Lee, I think I was unclear.
I'm not complaining about my throughput speeds on dialup as compared to the
theoretical ideal throughput speed. What I'm saying is this:
On dialup, a straight-forward FTP transfer to a host I'm getting
On dialup, going through the VPN to the same host and doing the same
operation, I'm getting 2.29Kb/sec.
So the same bandwidth constraints, other than the VPN device, and I drop
about 80% in performance.
Does this make a little more sense?
