										 | # node-uuid Benchmarks
 | ||
|  | 
 | ||
|  | ### Results
 | ||
|  | 
 | ||
|  | To see the results of our benchmarks visit https://github.com/broofa/node-uuid/wiki/Benchmark | ||
|  | 
 | ||
|  | ### 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](https://bitbucket.org/nikhilm/uuidjs) which is a wrapper around the native libuuid library. | ||
|  | * The `uuidjs()` entries are for Patrick Negri's [uuid-js module](https://github.com/pnegri/uuid-js) which is a pure javascript implementation based on [UUID.js](https://github.com/LiosK/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](http://www.gnuplot.info/) and [ImageMagick](http://www.imagemagick.org/) installed. You'll find a nice `bench.png` graph in the `benchmark/` directory then. |
