Hello Community,
since I have upgraded my debian 10 to 11, the read IO wait time of all
disks have been increased dramatically.
The hw and sw setup has not changed and there no extra IO related
activity on the server.
The scheduler is the same: mq-deadline. I have tried to set it to noop

There is a comparer/decider named UDS which holds an index of the valid
storage blocks, and a device driver named VDO which performes the
deduplication and hides its internals from the user by providing a
block device on top of the real stora

StarTech sells a $42 PCIe card with a parallel port and two
serial ports. If you're getting a desktop, this might be your
preferred path.

Correct, if you do always full backups then the second run will consume
full backup space in the first place. (not fully correct with bees

So they're antithetical concepts
