Hi
Yes if you loop 1000 times (or alot) then message history will take up
memory on the exchange as each step in the routes is recored by
default. You can turn this off
http://camel.apache.org/message-history.html
But as Brad says its not ideal to keep looping in Camel routes as they
are not intended to run forever/very long routes.
You can have higher performance from a java bean in a regular for loop
and then if needed use producer template to call a Camel route.
