> 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"/>
>         <!-- fake data to have something to work with -->
>         <setBody>
>             <groovy>['a', 'b', 'c', 'd']</groovy>
>         </setBody>
>         <setHeader headerName="raw">

> {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
