We have a major interest in using EMFT Compare and EMFT Search (Whenever
it will be available) for our toolings set. When I tried the simple
examples with smaller ecore models the code (obtained from the EMF Compare
FAQ under Headless Model comparisons) seems to be working fine. However
when I tried our own models that are fairly big in sizes (roughly 300k)
the code seems to be taking much longer for the
"DifferencesServices().modelMatch()" method. Its taking roughly one hour
just to give a good MatchModel back. However the code is later crashing
before doing any difference with "Java Heap Size" exception. I have tried
going to the max. heap size but it did not help with either the extreme
slowness of the first method as well as the Java heap exception. Question
is the code is it suppose to work mostly for relatively smaller model, if
not than can anybody make suggestion to improve the code operation?
