please note the WAL files are still on the raid 0 set which is still
in ext3 file system format. these test where run with the fsync as
before. I made sure every thing was the same as with the first test.
This is opposite to the way I run things. I use ext2 on the WAL and ext3
on the data. I'd also suggest RAID 10 on the WAL it is mostly write.
Just out of curiosity: Last time I did research, the word seemed to be that xfs was better than ext2 or ext3. Is that not true? Why use ext2/3 at all if xfs is faster for Postgres?
