This is correct attribute and it not ignored. There is just some special handling of this configuration in case version xsd used is 1.0 and upon upgrading it to 1.1 does some calculation for new defaults.
But in any case behavior you are describing is not part of it.

Can you try CR2 which has some more improvements in this area.
as general guideline, since 8.1 we try to smart calculate thread pool sizes for workers based on core count you have in your machine.

Also currently task-core-thread setting is not really used, as pool size is directly filled up to task-max-threads so no need for setting it.

Also currently task-core-thread setting is not really properly applied, as pool size is directly filled up to task-max-threads so no need for setting it.

> I tried to change the value of "task-core-threads" in web admin console to 128, but after restart it is set back to the default value 2. I searched in standalone.xml and didn't found any "128" in it.
> Then I guessed and tried to add an attribute "task-core-threads" in the work config xml but that made wildfly fail to start with an error like "worker node doesn't have attribute task-core-threads":
> {code:xml}
> <worker name="default" io-threads="8" task-max-threads="512" task-core-threads="128"/>
> {code}
> So, "task-core-threads" is just a fake? My app server now meets a performance bottleneck for http connections, how to change task-core-threads's value?
