> I don't know what the idea behind but in this class
> ([Producer|https://github.com/apache/camel/blob/master/components/camel-websocket/src/main/java/org/apache/camel/component/websocket/WebsocketProducer.java])
> sendToAll method the Thread.sleep in the while loop make all the process
> crazy slow just try to run this code
> {code:java}
> @Override
> public void configure() throws Exception {
> String uri =
> "websocket://127.0.0.1:8443/test?sendToAll=true&sendTimeout=0";
> from(uri).to(uri);
> }
> {code}
> and send multiple message to the server and you will see how slow is it for
> my point there is two defect:
> # Give the availability to send to all *expect* the sender
> # Fix the while loop
> During my test to have decent performance i set this parameter `sendTimeout`
> to 0 but i got this exception then:
