As you can see from April up until August the dumpsize increased
about 1.5 fold while the dump _time_ increased by a factor of
about 2.5. Dump rate dropped from 7.5 K/s to 4.6 K/s.
From August until now the dump size increased by about 10%
while dump time continues to grow dramatically.
I'll look into the "lots of small files added?" question.
Since your dumper and taper times are always nearly identical you probably
aren't using a holding disk and are dumping directly to tape. And since
the rates for one filesystem have remained constant while the other one has
dropped I would look into possible recent changes on the larger (slower)
filesystem. Try doing a dump to /dev/null and see how fast (or slow) that is.
If data isn't fed to the tape fast enough the tape drive has to stop and
reposition itself every time it runs out of data, which will slow it down
considerably.
