<p><img src="https://github.com/user-attachments/assets/870dc911-83a4-4f72-b114-60dee027238b" alt="image"></p>
<p>Then I remembered that I have spring template engine comparison benchmark <a href="https://ozkanpakdil.github.io/spring-comparing-template-engines/" target="_blank" rel="noopener nofollow">here</a> and I wonder how is JTE performance compared to thymeleaf or freemarker.
below is the latest numbers from <a href="https://github.com/ozkanpakdil/spring-comparing-template-engines/blob/master/result-23.txt" target="_blank" rel="noopener nofollow">java 23 build</a></p>

<p>JTE(2.9) is still slower than freemarker(2.6), it is still faster than jsp and mustache and thymeleaf. Also, <a href="https://github.com/ozkanpakdil/spring-comparing-template-engines/blob/master/result-21.txt" target="_blank" rel="noopener nofollow">here</a> you can see
older test results.</p>

JTE is a new template engine now listed in the Spring Boot starter site. While its performance (2.940 seconds) is slightly slower than Freemarker (2.616 seconds), it still outperforms JSP, Mustache, and Thymeleaf. Performance benchmarks for various template engines reveal JTE's competitive placement amidst alternatives.
