FWIW, I finally started to play around with this (or more precisely
https://lkml.org/lkml/2015/10/29/517). There were some prerequisite
changes in postgres required, to actually be able to benefit, delaying
things. First results are good, increasing OLTP throughput
considerably.
It'd also be rather helpful to be able to do
sync_file_range(SYNC_FILE_RANGE_WRITE) asynchronously, i.e. flush
without an implied barrier. Currently this blocks very frequently, even
if there's actually IO bandwidth available.
Regards,
Andres
