Dear Undertow devs,
I'm running some test on the new undertow subsystem: in particular I'm trying to
control the maximum threads available for serving http requests (old Tomcat maxThread
parameter).
Is it correct to define the max threads allowed via the io-threads attribute of the worker
element as follows ?
<subsystem xmlns="urn:jboss:domain:undertow:1.0">
<http-listener name="default" socket-binding="http"
worker="custom" />
. . .
</subsystem>
<subsystem xmlns="urn:jboss:domain:io:1.0">
<worker name="custom" io-threads="100" />
<buffer-pool name="default" buffer-size="16384"
buffers-per-slice="128"/>
</subsystem>
Or should rather use the task-max-threads attribute instead ?
Thanks!
Francesco

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.

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.

Thanks for the update @Tomaz @Stuart
Yes I managed to run a few JMeter test beds showing up that the task-max-threads has
control on the max number of concurrent requests That's what I was looking for.
Out of curiosity (sorry for raising some noise), what's the motivation for dropping
tomcat 7 fork and choosing undertow?
Thanks & Best regards
Francesco
