History

#1 Updated by Igor Sfiligoi over 5 years ago

I think some of the code can be streamlined pretty easily.
Working on it now.

As anticipated, the fix involved just smarter filtering of dictionaries.
The matchmaking time for CMS AnaOps went from about 20 mins to under 3 minutes...
(it is actually faster than in v3_2_3 now)

The code is in v3/6201.

Please review.
