The ExcaliburComponentManager is much slower, and will be the result of most
scalability
issues in Cocoon. The ContainerManager starts faster, and runs faster--even though it
does more work (with all the helper managers). The only area where ContainerManager is
slower is on shutdown, although it is not that much slower. There is one more
optimization
that will assist on ContainerManager's init time (currently pools are initialized in
the
constructor--that will be moved to the initialize() method).
