Hi,

this page:
https://projects.eclipse.org/projects/modeling.emf.emf/reviews/2.9.0-release-review

states that 2.9 includes significant (runtime?) performance
improvements. Can you give a concrete example on what improved?

Thanks,
Felix

Felix,

The URI implementation was completely rewritten to parse URIs faster and
to minimize the heap footprint. E.g., there is only a single instance
of a URI with a given string representation in the VM (so == and .equals
are the same for fragmentless URIs), all segments are pooled, and even
the fragments are segmented with pooled substrings.
