Further to the confusion, here's my 9.3 vs 9.4 on two M550 (one for 9.3
one for 9.4), see below for results.
I'm running xfs on them with trim/discard enabled:
$ mount|grep pg
/dev/sdd4 on /mnt/pg94 type xfs (rw,discard)
/dev/sdc4 on /mnt/pg93 type xfs (rw,discard)
I'm *not* seeing any significant difference between 9.3 and 9.4, and the
numbers are both about 2x your best number, which is food for thought
(those P320's should toast my M550 for write performance...).
cool! any details on OS and other options? I still get the same numbers
as before.
Sorry, Ubuntu 14.04 on a single socket i7 3.4 Ghz, 16G (i.e my workstation).
I saw the suggestion that Didier made to run 9.3 on the SSD that you
were using for 9.4, and see if it suddenly goes slow - then we'd know
it's something about the disk (or filesystem/mount options). Can you
test this?
Cheers
Mark
