Bug 182337 shows that current design of org.eclipse.core.contenttype.contentTypes extension point lacks scalability.

This is because each contributed content type can declare it's own describer. Since describers are customizable they are instantiated one per each type. During the process of determining the content type each one of these instances parses the input which introduces a great performance hit.

Bug 182337 narrows the problem to few classes responsible for describing XML files. This one aims at solving it comprehensively.

Do you have a proposal of how to improve the scalability, but still provide the power of the ContentTypeDescribers?
