Thymeleaf 3.0.0 is now released and could be curious to see the performance improvement.

As brought up by @mkouba in pull request #3, my recent modifications might have given mustache an unfair advantage. Before the benchmark begins it does some pre-processing on the data; processing that other templates don't have a chance to do until the are being timed.

For embedded projects that require templating

Please add Jtwig to comparision.

This is the result of running on my computer.
The environment:

JMH 1.11.2 (released 1765 days ago, please consider updating!)

VM version: JDK 1.8.0_211, VM 25.211-b12

16 GB 1600 MHz DDR3

2.2 GHz quad-core Intel Core I7

The output is not the same for all templating engines.

stocks.mustache.html:

1. ${["odd", "even"][item_index%2]} is ignored so don't get the correct class for odd/even rows
2. ${item_index + 1} is ignored so don't get the index
3. negative values are not wrapped with <td class="minus">

You should either remove these parts from all templates or implement this with mustache.java (I think you would have to implement some TemplateFunction to get the same functionality).

Also I would add a test to compare the output of all benchmarks.

The Rocker template does not check if the "minus" class should be applied or not. The class is always set!

Example:

<td class="minus">@item.getChange()</td>

So, the results are not similar, and the benchmark is not fair.

The data file contains "com.mitchellbosecke.benchmark.Freemarker.benchmark", the plot currently transforms that into "Freema", but ideally the plot will display "Freemarker".

I don't know enough about gnuplot to fix this.

HtmlFlow is a Java DSL to write typesafe HTML documents.

HtmlFlow competes with the most performant template engine, i.e. Rocker and is faster than the remaining concurrency.

HtmlFlow is widely used to build dynamic HTML documents, such as papers, reports, emails, etc, involving complex programing tasks which are hardly achieved through textual templates. Moreover, HtmlFlow can also be used as a web template engine allying its performance boost with its HTML strongly type safety characteristics.
