It seems like XFS only allows you to mount a volume with a block size the same as the OS memory PAGE_SIZE. Ideally, I would like to get a better transfer rate from block storage, but I am being limited by the IOPS rate well before my BW limits are hit. I attempted to reform an XFS partition with a large block size but was unable to mount it due to the limitations able.
Is this limit also true of ext4? Does Digital Ocean have ubuntu versions compiled with large kernel PAGE_SIZES available? How would you suggest setting up a droplet for maximum block storage performance?
