We've got some simple benchmark results for larger data sets within
Org-mode files:

https://github.com/novoid/Memacs/blob/master/performance.org
(Sorry, «many Org-mode files» was no issue at our side, so we did
not research into that.)

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.
