template-benchmark
================

JMH benchmark for the the most popular Java template engines.

1. Download the source code and build it (`mvn clean install`)
2. Run the benchmark suite with `java -jar target/benchmarks.jar`

Rules of Template Engine Configuration
======================================
It is imperative that each template engine is configured in way to reflect real-world usage as opposed to it's *optimal* configuration. Typically this means an out-of-the-box configuration.

To strive for a common set of features across template engines, the following configurations are expected:
* Disabling of HTML escaping
* Template loaded from classpath prior to actual benchmark

Interpreting the Results
========================
The benchmarks measure throughput, given in "ops/time". The time unit used is seconds. 
Generally, the score represents the number of templates rendered per second; the higher the score, the better.

Example Output
===============
The following benchmark was run on a machine with the following stats:

* OS: CentOS 7
* Kernel: 3.10.0-123.el7.x86_64
* Memory: 8GB
* Processor: Intel(R) Core(TM) i5-3470 CPU @ 3.20GHz
