depending on your origin and your users, having TLS terminate / be negotiated at the edge should _reduce_ your connection setup cost, by reducing RTT time for the handshake to the end user (typically the slowest bit / longest tail).

If you have 1 origin region/server and globally distributed users, in the data shown the RTT from Sydney could be 1000ms, so TLS negotiation of 3 roundtrips could be 3000ms. If you terminate TLS at the edge that could be order of magnitude less.. not more? depends on your setup though.

This is true, on average having an edge will be faster, but it is not a panacea for latency, especially if you don't move non-trivial QPS from every region.
