> We noticed some performance issues with the execution of Groovy expression. In the {{GroovyExpression}} the script is parsed 2 times at each evaluation. You'll find attached a patch that caches the parsed-version of the scripts.
> We did some performance tests with the following definition:
> {noformat}
> from("direct:start")
>     .loop(10000)
>     .setBody(new GroovyExpression("request.body + request.getHeader('CamelLoopIndex')"))
>     .to("mock:ignore");
> {noformat}
> We took the average of 5 executions (without the first one):
> || use case || duration ||
> | default, no cache | 52690ms |
> | patched, with cache | 1017ms |
> It's more than 50 times faster which is always nice to have
