Which test node has the lowest latency (RTT)

RE: Which test node has the lowest latency (RTT)
Hi Pat,

i was using the Dublin node, but found i couldn't get better than about 50ms latency in my tests (using native). So despite it being set to DSL 28ms it couldn't get that low.

I'll repeat the tests from your basement ;-)

Dulles tends to work really well as well but it does have ~4ms of latency on the connection itself (should be subtracted out from the traffic shaping).

What are you measuring RTT to? Your server or a CDN edge node? Some of it will depend on the natural network latency from the physical location to the server being hit (and in the case of a CDN it will also depend on how good they are at picking the best edge node).

You can try running at "Native" speed which will show you the natural latency on a given test node to the servers being tested.
