    EJB thread pool analysis in WildFly-8.2

    valsaraj viswanathan Master

      We have run load test with single user submitting 100 forms.

       

      EJB pool is set as:

                     <thread-pools>

                          <thread-pool name="default">

                              <max-threads count="250"/>

                              <keepalive-time time="100" unit="milliseconds"/>

                          </thread-pool>

                      </thread-pools>

       

      Before test:

      /subsystem=ejb3/thread-pool=default/:read-resource(include-runtime=true)

      {

          "outcome" => "success",

          "result" => {

              "active-count" => 0,

              "completed-task-count" => 2L,

              "current-thread-count" => 2,

              "keepalive-time" => {

                  "time" => 100L,

                  "unit" => "MILLISECONDS"

              },

              "largest-thread-count" => 2,

              "max-threads" => 250,

              "name" => "default",

              "queue-size" => 0,

              "rejected-count" => 0,

              "task-count" => 2L,

              "thread-factory" => undefined

          }

      }

       

      After test:

      {

          "outcome" => "success",

          "result" => {

              "active-count" => 0,

              "completed-task-count" => 389L,

              "current-thread-count" => 250,

              "keepalive-time" => {

                  "time" => 100L,

                  "unit" => "MILLISECONDS"

              },

              "largest-thread-count" => 250,

              "max-threads" => 250,

              "name" => "default",

              "queue-size" => 0,

              "rejected-count" => 0,

              "task-count" => 389L,

              "thread-factory" => undefined

          }

      }

       

      It looks like pool is filled. Forms are submitted one by one. Then why it is not reused? Can anybody help on analyzing this case?
