Default slsb-strict-max-pool size in Wildfly 10

Question

On wildfly 10 server startup we get slsb-strict-max-pool as 64

2017-08-24 12:51:09,164 INFO  [org.jboss.as.ejb3] (MSC service thread 1-5) WFLYEJB0481: Strict pool slsb-strict-max-pool is using a max instance size of 64 (per class), which is derived from thread worker pool sizing.
2017-08-24 12:51:09,166 INFO  [org.jboss.as.ejb3] (MSC service thread 1-5) WFLYEJB0482: Strict pool mdb-strict-max-pool is using a max instance size of 16 (per class), which is derived from the number of CPUs on this host.

But when I execute below for jboss-cli then the **max pool size is 20** as shown in the below image

/host=master/server=server-one/subsystem=ejb3/strict-max-bean-instance-pool=slsb-strict-max-pool/:read-resource(recursive=false)

Exactly what is the default max pool size of ejb in Wildfly 10 ??

Answer 1

The pool size is dynamic by default because it is derived from the worker thread-pool size ("derive-size" property). So in your case you have 4 CPU cores and get a pool size of 64. The max-pool-size value is ignored in this case so what the wildfly interface is saying is the correct runtime value.
