Choosing Templating Engine is a little complex job when it comes to Java. There are several Java-based templating engines such as Freemarker, HTTL, Mustache, Pebble, Rocker, Thymeleaf, Velocity etc.
I just picked up the Benchmark code from https://github.com/mbosecke/template-benchmark and added HTTL template engine as part of the benchmark.
Here is the Updated Code and the Benchmark
Note: Score is nothing but "Templates rendered per second"
HTTL still stands #1 position.
