Another limitation is that OSDs should store 100 PGs each regardless of their size, so those PGs will each need to store many more objects and therefore recovery, scrubbing, removal, listing, etc... will all take longer and longer. So perhaps we'll need to change the OSD to allow for 500 or 1000 PGs per OSD eventually, (meaning also that PGs per cluster needs to scale up too!)
