comment Does a ping to 127.0.0.1 hit the network card? Which RFC / standard states that?
This is one of those type of exam questions that is too easy to "overthink". For example, two virtual machines on the same host could in theory do "networking" without any network card; so, in short, you won't find this: "I need an official source saying that pinging 127.0.0.1 does not hit the network card." The answer to the question is simply (probably) "yes", as it is a useful first diagnostic step that is "necessary but not sufficient" to determine if networking is configured.

comment Will a SQL incremental backup work for my purposes?
@longneck at the risk of hand-waving, the performance difference between theory & practice can be significant, but I get what you're saying. Tony - if you have considerable time and a large budget, GoldenGate (an Oracle acquisition) does this (disclaimer: I worked there but no longer do). You can quickly prototype a solution (for free) by downloading from OTN and experiment with theoretical max transfer rates.

comment Can VPNs reduce latency?
@VinkoVrsalovic right, exactly. encryption itself isn't enough to make yourself "private", no more than a ski mask makes one invisible in broad daylight; so, ISP's just poke everyone they don't recognize with a sharp stick just to hear 'em squeal (and they'll stop only if they recognize your voice). VPN's turn out the lights, so all they hear is the pitter-patter of footprints in the dark. It's a relatively sharp-stick-free environment. (Apologies for the extended metaphors; I'm just entertaining myself.)

comment Can VPNs reduce latency?
The question To VPN or Not To VPN is, in this case, unrelated to routing, but rather the intentional throttling (traffic shaping) or intentional disrupting (e.g., TCP reset ) of your connection. The VPN hides your conversation from your ISP, who may be engaged in a malicious meddler-in-the-middle "attack".

(originally posted as a comment to the other answer (which I agree with), but my response became too long to fit as a comment.)

comment Can VPNs reduce latency?
Btw, encryption is different than VPN. You can have encrypted data that is treated differently than data over a VPN; e.g., comcast purportedly uses a network filter application (sandvine) that intentionally disrupts non-comcast user's connections (sending a TCP/IP reset (RST) flag); a VPN should prevent this type of "attack". (footnote: the fcc actually ordered comcast to stop doing this, but at some point they might author/pass legislation that allows/encourages it again.)

comment Can VPNs reduce latency?
This is marked as a duplicate, but the other question is for office-to-office VPN; this is for gamers and game servers. All things being equal, this would be a duplicate. But things today are not equal. Your ISP (Comcast, ATT) will almost certainly be throttling your traffic (or at least someone's traffic, if multiple players are involved). The only way to prevent this (other than technological subterfuge) is through legislation that guarantees net neutrality. (Search for: vpn + traffic shaping {comcast|att})

comment Can VPNs reduce latency?
The gods unfortunately are unkind, and can choose to change the physics of the internets for us helpless mortals at their whim. The gods being of course Comcast (properly uppercased as canon dictates), and we must play by their rules. Masking our presence, trafficking in private networks, may stave off Their capricious ways, if only for the time being. Fare thee well, traveller.
