Hi all,

We've been using EMF Compare inspired routines in the Eclipse Open
Healthcare Framework project for comparison of some large (and unfortunately
not EMF) models.

When doing a performance sweep, we noticed that
org.eclipse.emf.compare.match.statistic.similarity.NameSimil arity.pairs()
has an unnecessary toUpperCase() method in a loop which is responsible for
creating a lot of objects.

Removing this reduced our match times from 264 seconds to 23 seconds.

Thanks for all your hard work,
Brandon

Brandon,

This was one of the methods I was trying to tweak for improvements and
this one has a major impact on comparison time indeed.

Thanks for letting us know.
