--------------------------------------------
Good benchmark to test performance would be [https://jte.gg/,]

> Close Performance Gap in Groovy Templates
> -----------------------------------------
>
> Key: GROOVY-9716
> URL: https://issues.apache.org/jira/browse/GROOVY-9716
> Project: Groovy
> Issue Type: Improvement
> Components: Templating
> Reporter: Suminda Dharmasena
> Priority: Major
>
> Groovy Templates seams to be comparatively less performant than other
> templating solutions. E.g.:
> [https://github.com/jreijn/spring-comparing-template-engines]
>
> Can this performance gap be closed making it the most performant?
>
> Also is it possible to add partials evaluation support when only parts of the
> template need reevaluation when part of the data changes.
>
> Possible areas to improve:
> * Faster reflection can be used like used in:
> [https://github.com/EsotericSoftware/reflectasm]
> * Be lock-free as much as possible. Maybe
> [disruptor-proxy|https://github.com/LMAX-Exchange/disruptor-proxy] pattern
> can be used but with [Conversant
> Disruptor|https://github.com/conversant/disruptor] limited to the methods
> which need synchronising
> * Use faster primitive collections
> * Use faster logger like Log4J2 with [Conversant
> Disruptor|https://github.com/conversant/disruptor]
> NB: This benchmark may be dated but some outperform stringbuilder:
