[jira] [Created] (CAMEL-6340) Improve Groovy performance
Antoine DESSAIGNE created CAMEL-6340:
----------------------------------------
Summary: Improve Groovy performance
Key: CAMEL-6340
URL: https://issues.apache.org/jira/browse/CAMEL-6340
Project: Camel
Issue Type: Improvement
Components: camel-groovy
Affects Versions: 2.10.3
Reporter: Antoine DESSAIGNE
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
