Yes, and piecewise TCP is often even faster than point-to-point TCP, especially on flaky connections, or when the transient connections are on hosts with lower RTTs (outgoing gateway closer to destination). It will likely be faster than a UDP VPN. It still does have overhead, so lower bandwidth. Also, TCP, SSH and/or TLS forwarding of UDP, IP or Ethernet can have issues with delays, re-transmits etc (TCP-in-TCP).
