template-benchmark

JMH benchmark for popular Java template engines:

• Freemarker
• Mustache
• Pebble
• Rocker
• Thymeleaf
• Trimou
• Velocity

Running the benchmark

1. Download the source code and build it (mvn clean install)
2. Run the entire benchmark suite with java -jar target/benchmarks.jar
3. (Optional) To run a single benchmark, such as Mustache, use java -jar target/benchmarks.jar Mustache

Generating plot

1. Run benchmark while exporting results to csv with java -jar target/benchmarks.jar -rff results.csv -rf csv
2. Use gnuplot to generate plot with gnuplot benchmark.plot. This will output results.png.

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.
