Hi Folks, The performance meeting will be starting in roughly 20 minutes! Today Gabi would like to give an update on his bluestore allocation optimization work (25%+ random write performance increase!) and Adam and I will give an update on the investigation into the bluefs_buffered_io=disabled performance investigation (hint, it looks a lot like range scan iteration is not effectively coming from block cache in some cases).  Hope to see you there!
