Martin Kouba commented on AS7-4226:
-----------------------------------

Well I'm not completely sure it's all just about HTTP connection timeout. At least it is not obvious from the spec wording. Imho it's also about timeout for the asynchronous processing which might be more fine-grained. However I'm ok with resolution. The only thing I do not understand is time unit (ms) used in {{javax.servlet.AsyncContext.setTimeout(long)}}. This is confusing and makes no sense.

> The async servlet operation timeout check is run approx. every ten seconds. This is not very practical/precise assuming the timeout is specified in milliseconds -> {{javax.servlet.AsyncContext.setTimeout(long)}}.
> Not completely sure about the exact time - 10s occures in my simple CDI TCK test). Looking at {{org.apache.tomcat.util.net.JIoEndpoint#Poller.maintain()}} five seconds is hard coded minimum: "Maintain runs at most once every 5s".
> I suppose this is intentional and due to performance reasons. If so it should be FAQed or mentioned in docs. Otherwise it should be fixed.
