Ricardo Martin Camarero commented on WFCORE-4768:
-------------------------------------------------

It seems the message is confusing for some users. The current options in the CLI interface are:

{noformat}
            "io-threads" => {
                "type" => INT,
                "description" => "Specify the number of I/O threads to create for the worker.  If not specified, a default will be chosen, which is calculated by cpuCount * 2",
                "expressions-allowed" => true,
                "required" => false,
                "nillable" => true,
                "min" => 0L,
                "max" => 2147483647L,
                "access-type" => "read-write",
                "storage" => "configuration",
                "restart-required" => "all-services"
            },
            "task-max-threads" => {
                "type" => INT,
                "description" => "Specify the maximum number of threads for the worker task thread pool.If not set, default value used which is calculated by formula cpuCount * 16,as long as MaxFileDescriptorCount jmx property allows that number, otherwise calculation takes max into account to adjust it accordingly.",
                "expressions-allowed" => true,
                "required" => false,
                "nillable" => true,
                "min" => 0L,
                "max" => 2147483647L,
                "access-type" => "read-write",
                "storage" => "configuration",
                "restart-required" => "all-services"
            }
{noformat}

So we are going to change the messages (there are four messages for these two auto-configured values):

* "XX core threads" => "XX IO threads"
* "XX task threads" => "XX max task threads"

> [org.wildfly.extension.io] (ServerService Thread Pool -- 52) WFLYIO001: Worker 'default' has auto-configured to 24 core threads with 192 task threads based on your 12 available processors
> The IO subsystem by default picks values for the thread default sizes.
> The '24 core threads' is actually io-threads
> The '192 task threads' is the 'task-max-threads'
> The task-core-threads looks like it actually defaults to 2
> It would be better to change '24 core threads' to '24 IO threads' and 192 task threads'  to 192 max task threads'
