Antoine DESSAIGNE updated CAMEL-15715:
--------------------------------------
Description:
Hello everyone,
We identified a performance drop in Simple expressions in 3.4.4 compared to
2.25.1
Given the following route
{code:xml}
<?xml version="1.0" encoding="UTF-8"?>
<routes xmlns="http://camel.apache.org/schema/spring";
xmlns:u="http://www.systar.com/aluminium/camel-util";>
<route>
<from uri="timer:foo?delay=-1&repeatCount=1000000"/>
<setBody>
<groovy>['a', 'b', 'c', 'd']</groovy>
</setBody>
<setHeader headerName="raw">
<simple>${body[2]}</simple>
</setHeader>
<setHeader headerName="string">
<simple resultType="String">${body[2]}</simple>
</setHeader>
<setHeader headerName="constant">
<constant>constant</constant>
</setHeader>
<to uri="log:throughput?groupInterval=1000"/>
</route>
</routes>
{code}
In Camel 3.4.4 I have an average of 10,324 messages per second whereas I have
an average of 69,662 messages per second in Camel 2.25.1
When extracting JMX {{TotalProcessingTime}} attribute on the {{setHeader}}
processors here what I have for the 1 million messages
||SetHeader||Camel 2.25.1||Camel 3.4.4||
||raw|4506|45275|
||string|3935|44103|
||constant|377|470|
We're using an OSGi environment but I don't think it has an impact here.
Can you have a look? What can I do to help?
Thank you
