node-benchmark-pages

A library for benchmarking your web service.

Suppose you want to measure the average response time of your service under a typical load scenario. This library allows you to declare such a scenario (in terms of pages and their frequency) and then measure their average response time under a different loads (different simultaneous requests limits). Various statistical methods are available for the raw measurements data; the library may also output the statistical data into the console in the convenient form if you like.

Another use case is when you have more than one version of the same service and want to compare their response time or maximum load.

Examples

See the example directory.

Installation

$ npm install cacheio

Notes

It makes little sense to measure the remote services, as the result will generally depend of your network connection and not of your service performance.

Also, the library assumes service responses are consistent. That is, it assumes that, for any given engine and page, the response length will not change over the time. If suddenly your service sent a response of a different length, the library assumes something went wrong, writes an error into your console, and does not use this data when computing statistics.

Currently, you're only limited to a single running benchmark per process. It is related to a global http.globalAgent.maxSockets variable.
