If the connection is like this:

and the VPN is doing crypto as well as NAT, it might be slower, because
you're getting double-encrypted.
If your VPN is set up enough that its translation is "invisible" to you,
it may be faster to an end user type (hint: latency, not bandwidth, nor
You can set up ssh keys and your .profile such that you get a very clean
"double hop" through the gate... but I don't advise it.

what if someone hacks your gateway box?
So startup should be slower, you'd want to type two passphrases. But the
connection may be faster for certain kinds of things. Specifically, things
which don't send once character at a time back through the double hop.
But, you can have an alias with the snarky ssh commandline. And you don't
have to depend on the VPN admins.
