See my reply above. My 250 tps seems in line with the 700 tps on a modern

regards,
I am hoping your assumptions are correct. I have reinstalled ubuntu from
scratch as I had been tinkering with the power management on the server.
Once the RAID has rebuilt, I shall try again.
What kind of file system are you running?
regards,
The file system is ext4. If I turn fsync off I get a TPS of 1120 so I
think there is an issue with the speed of the array.
The dd test give a speed of 125MB/s which seems reasonable to me.
I can leave fsync off but I suspect that I am just ignoring the problem.
