Thank you for the hint, I was just profiling my application, and noticed
that with modified XMLFileDescriptorStore every request need 1200 ms, and
that with a full cacheable pipeline.
After solving a problem with the cache of XMLFileDescriptorStore I
went into <100ms.

Ps. I don't want to cache the Sources within the Generator, but the
current SourceResolver doesn't handle pools of Sources.

Stephan.
