How to tune Camel Rest?

Issue

I am using Camel Rest in my project, it based on Springboot + camel + Fuse on OCP.
my code is like:

        <restConfiguration bindingMode="auto" component="jetty"
            contextPath="/fuse" host="0.0.0.0" port="20080"/>
        <rest id="eai-rest" path="/eai-rest">
            <post consumes="application/json; charset=utf-8"
                id="rest-post" produces="application/json; charset=utf-8">
                <to id="direct to eai-gw-rest" uri="direct:eai-gw-rest"/>
            </post>
        </rest>
        <route id="eai-gw-rest" streamCache="true">
            <!-- convert request to byte array -->
            <from id="fromREST" uri="direct:eai-gw-rest"/>

I want to know :

• the default thread count, how to change its value?
• how to change connection/idle timeout?
