It was pointed a news which was related to an improvement (fetch support) which brought memory usage optimization in usrloc (going to be expanded in usage to other modules, like lcr, presence ...), not usrloc loading/lookup optimization. It was not yet a news since the work is not fully finished/well tested. The news about this new improvements will come in the near future. It started in summer, with:

CAn someone help with the questions
- retransmission: can't there be inconsistence of data during initial DB loading?
- performance: can comeone confirm for me that the acclaimed memory saving are
  not achievable, as suggested in Andrei's email

assumptions, it appears one-process-loading+others-as-normal -- it that what
it does?

Thanks!
