Hi,

we are currently facing performance issues whilst loading large size EMF model resources.

are there any tips and techniques we can use/implement to improve EMF performance for loading, saving, in-memory manipluation of large model resources?

so far on this topic, i have found only the following article

http://www.eclipse.org/modeling/emf/docs/performance/EMFPerf ormanceTips.html

any other help/pointers would be much appreciated.

thanks,

- Hemant

Hemant,

No matter how highly performance tuned something might be, it's always
possible to exceed system capacity. In your case it sounds like
instances are just very huge so
http://ed-merks.blogspot.com/2008/10/how-big-is-eobject.html would
likely help, but even with smaller straws it's still possible to break
the camel's back. CDO would help, but not so much if you need to load
and save large XML instances:
