Sorry, but why is that?  And do you mean read performance, write
performance or both?  And is that a factor of the type of storage
(e.g. spinning disk vs. SSD)?

Sure, I didn't suggest eliminating the reservation, just reducing it.
Or is there some reason that root would need at least 5% (as opposed
to 1% or 2%) of disk available to write to that I'm missing?

While that may be true of Ubuntu on the client (desktop, laptop,
tablet, phone, etc.); I'm not sure it's true of server and cloud?
