Re: [undertow-dev] Undertow worker threads
Afaik we have replaced task-max-threads for io-threads as per dissucstion I
had with David.
Probably David can tell bit more.
Francsco, what are you after? Limiting the number of concurrent requests or
just threads processing requests?
As in undertow few threads can process lots of requests concurrently we do
not have 1:1 mapping on thread:request as jbossweb/tomcat did.

You are after task-max-threads (we probably need a better name for this).
io-threads are just used for accepting and parsing HTTP requests, once the
request is parsed it is handed off to the task threads to actually run the
servlet request.
