Forgive the top-post.
The reason why this particular case of an extremely slow Manager upload sticks
out is because we've done, by now, hundreds of uploads of this same WAR file
(or earlier versions of it), via Manager, on over a dozen different
installations, most of them AS/400s, and none of the others have taken even
half this long.
The problem might be deeper than tomcat then.

Have you ruled out IO problems writing the WAR? Is the HD/SSD failing and
trying to resolve bad blocks? Is the network device failing causing dropped
packets?
Has another process on the machine run amok and causing IO contention, or
paging issues?
With the information available so far, it is a bit hard to make a qualified
guess.
If you can do this, and you have a choice of WARs to upload to the same system, and as a
first simple way of getting more information, I would try uploading e.g. a WAR that is 50%
or 25% or 10% the size of that original one, and see if the times are consistent with your
50 MB WAR.
And do this several times, to see if the times are consistent for the same size, or they
vary widely over time.
Uploading another WAR will use exactly the same steps and elements as your first try,
varying only one item at a time : the size of the upload.
