Benchmark two ways to fetch the current machine's public IP address from the command-line.

Benchmark two "get my IP" commands

Benchmark two ways to fetch the current machine's public IP address from the command-line.

Setup: install Node.js and npm. Execute npm install to fetch dependencies.

index.js is the real test. Run it with node index.js. Example output:

HTTP x 5.19 ops/sec ±7.38% (31 runs sampled)
DNS x 17.48 ops/sec ±5.02% (48 runs sampled)
Fastest is DNS

That's from a 4-core 1.80GHz Intel Core i3 laptop running 64-bit Ubuntu 14.04.02 LTS.

"HTTP" measures curl http://canhazip.com.

"DNS" measures dig +short myip.opendns.com @resolver1.opendns.com.

simple.js is a simple "control" to show that the way I'm benchmarking more or less makes sense. Output should show that sleep one second takes one second to run and is twice as fast as sleep two seconds. Example output:

sleep two seconds x 0.50 ops/sec ±0.16% (7 runs sampled)
sleep one second x 0.99 ops/sec ±0.15% (9 runs sampled)
Fastest is sleep one second
