could you please try those iodepth=20000 tests with the latest
fio-testing branch of fio as well? Jens wrote a new, smarter syslet
plugin for FIO. You'll need the v3 syslet kernel plus:

git-clone git://
cd fio
git-checkout syslet-testing

my expectation is that it should behave better with iodepth=20000
(although i havent tried that yet).
