In short: * Best performance: only without any drawers at all * Acceptable performance when using another drawer than :PROPERTIES: * Worst performance when using :PROPERTIES: drawer So if you want to have many entries in Org-mode files, avoid drawers if you can. If you need a drawer, probably choose to define your own drawer. -- Karl Voit
