Hello friends of the forum, already I am finishing my portal in gatein for a company but I notice that the time of response is very slow.
 
What must I do to improve it?

Someone that I have applied

Lots  of Requests ?  check JBoss thread pool

JBoss thread pool is defined into conf/jboss-service.xml

For most applications this defaults will just work well, however if you   are running an application with issues lots of requests to jboss (such   as EJB invocations) then monitor your thread pool. Open the Web  Console  and look for the MBean jboss.system:service=ThreadPool.

Start a monitor on the QueueSize  parameter. Have you got a QueueSize which reaches MaximumPoolSize ? then probably  you need to set a higher MaximumPoolSize pool size  attribute

Set -Xms  and -Xmx to the same value

By default, the virtual machine grows or  shrinks the heap at each collection to try to keep the proportion of  free space to live objects at each collection within a specific range.

Setting -Xms and -Xmx to the same value. This  increase predictability by removing the most important sizing decision  from the virtual machine.
