Hi all, Inventory 0.15.0.Final had a serious performance regression in the bulk insert. The 0.15.1.Final fixes that problem and the performance should now be on the same order of magnitude as previously (still 0.15.x is slower on creates, updates and deletes than 0.14.x thanks to the new identity hashing functionality). Please update as soon as possible, Thanks, -- Lukas Krejci
