Run them yourself

node-uuid comes with some benchmarks to measure performance of generating UUIDs. These can be run using node.js. node-uuid is being benchmarked against some other uuid modules, that are available through npm namely uuid and uuid-js.

To prepare and run the benchmark issue;

npm install uuid uuid-js
node benchmark/benchmark.js

You'll see an output like this one:

# v4
nodeuuid.v4(): 854700 uuids/second
nodeuuid.v4('binary'): 788643 uuids/second
nodeuuid.v4('binary', buffer): 1336898 uuids/second
uuid(): 479386 uuids/second
uuid('binary'): 582072 uuids/second
uuidjs.create(4): 312304 uuids/second

# v1
nodeuuid.v1(): 938086 uuids/second
nodeuuid.v1('binary'): 683060 uuids/second
nodeuuid.v1('binary', buffer): 1644736 uuids/second
uuidjs.create(1): 190621 uuids/second

• The uuid() entries are for Nikhil Marathe's uuid module which is a wrapper around the native libuuid library.
• The uuidjs() entries are for Patrick Negri's uuid-js module which is a pure javascript implementation based on UUID.js by LiosK.

If you want to get more reliable results you can run the benchmark multiple times and write the output into a log file:

for i in {0..9}; do node benchmark/benchmark.js >> benchmark/bench_0.4.12.log; done;

If you're interested in how performance varies between different node versions, you can issue the above command multiple times.

You can then use the shell script bench.sh provided in this directory to calculate the averages over all benchmark runs and draw a nice plot:

(cd benchmark/ && ./bench.sh)

This assumes you have gnuplot and ImageMagick installed. You'll find a nice bench.png graph in the benchmark/ directory then.
