Roman, It has been reported when using the rebuilder with 7zip sets (Hash collision all clones in relationship) - (Full Merge Mode - Hash collision name)
I see while rebuilding is taking place It constantly packs and unpacks the 7zip file for every single change that it makes. In other words It opens (unzips) and closes (compresses) the 7z file for each change to each containing set instead of opening it once, make all the changes and then close it.
Is there anyway to make this operation to be more efficient as in open the 7z once and close it when all changes have completed?
Please see this in action for yourself using HBMAME and set kof2001
