Parallel execution of portlets (repost from User list)

["NAJMAN Yves - SOP ( YNajman@sophia-antipolis.sema.slb.com )" <YN...@sophia-antipolis.sema.slb.com>]

As it was proposed by Raphael Luta, let's continue on the Dev list.

Summary: How to execute portlets in parallel?

2 solutions proposed:

1) from Josh Hone:

> If you are familiar with velocity, it amounts to subdividing the Context.

2) from Raphael Luta:

> Jetspeed and will welcome the patch :)

At the moment, I do not know which one is best.

Definitly, it would be nice to be able to flag a portlet as "parallel
execution candidate": this would avoid to to start parallel execution of all
portlets.

As threads are involved, it seems reasonable to use a thread pool (as far as
I know, creating/destroying threads can be very hungry at system resources,
it is necessary to recycle them): is there a thread pool already in place in
JetSpeed/Turbine/Tomcat that can be used for that purpose.

Note: at the moment I have very few spare time to spend on the subject and I
am very new to the whole stuff (JetSpeed/Turbine). I hope nobody have an
urgent need for this feature :-)
