The dump time is increasing way beyond the growth rate of data
to be dumped.

See below.
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.
Thanks,
