**NeDB is not intended to be a replacement of large-scale databases such as MongoDB!** Its goal is to provide you with a clean and easy way to query data and persist it to disk, for web applications that do not need lots of concurrent connections, for example a <a href="https://github.com/louischatriot/braindead-ci" target="_blank">continuous integration and deployment server</a> and desktop applications built with <a href="https://github.com/rogerwang/node-webkit" target="_blank">Node Webkit</a>.
As such, it was not designed for speed. That said, it is still pretty fast on the expected datasets, especially if you use indexing. On my machine (3 years old, no SSD), with a collection
containing 10,000 documents, with indexing:
* Insert: 6,180 ops/s
* Find: 42,370 ops/s
* Update: 4,730 ops/s
* Remove: 3,750 ops/s
containing 10,000 documents, with indexing and no pipelining:
* Insert: **6,180 ops/s**
* Find: **42,370 ops/s**

* Remove: **3,750 ops/s**
You can run the simple benchmarks I use by executing the scripts in the `benchmarks` folder. Run them with the `--help` flag to see how they work.
