mainly two sets of mid-sized files; one of 200KB-2MB in size and other under
50KB. they are organised into subdirectories, A/B/C/<file>. each directory
has 18,000-25,000 files. total data size is around 2.5TB.
hm, something changed while i was writing this mail: now the transfer is
running at 2MB/sec, and the read i/o has disappeared. that's still slower than
i'd expect, but an improvement.

i'd rather not interrupt the current send, as it's quite large. once it's
finished, i'll test with smaller changes...
