ok, thanks.

So, I see that you are in a point where you are doing some performance tests for your application.
I wonder if you are using the concurrent mode of dependency manager ?
Mixing DM filter indices + DM concurrent mode may significantly reduce startup time, especially
if you have thousands of components which have some time consuming start methods.

DM concurrent mode has a kind of actor model: each component remains "single threaded" (all
osgi events are handled serially), but multiple distinct components can be started concurrently.
In case you are interested, don't hesitate to ask on the users mailing list, I will provide
support. you can check [1] for general description about DM concurrent mode, and [2] for a
concrete example (in the example, I'm using a pattern which allows to specify whether or not
a given component can be started in a given thread pool, or if it must be handled synchronously,
as it is the case by default, but you can also have a model where all components are by default
started concurrently).

[2] http://svn.apache.org/viewvc/felix/trunk/dependencymanager/org.apache.felix.dependencymanager.samples/src/org/apache/felix/dependencymanager/samples/tpool/

hope this helps;

> The code in InvocationUtil to set a custom size for the method cache has been commented
out. See InvocationUtil.java.
> The default is not large enough for me.
