@ncw for instance: https://developers.google.com/drive/v3/web/manage-uploads#resumable Is this a possibility in rclone?

Should this be moved to https://github.com/apache/couchdb-fauxton ?

@vincentkfu i am most interested in testing synchronous writes. This is also the recommended test here: https://docs.ceph.com/en/quincy/start/hardware-recommendations/ I would do sync=1, but that doesn’t seem to have an affect on...

@vincentkfu would you happen to have any insight into this? Am I doing something incorrect/unexpected as far as fio is concerned?

@ooptimum when I check with hdparm, I get unsupported: ``` # hdparm -W /dev/sda /dev/sda: write-caching = not supported ```

@ooptimum actually, I was able to do this with sdparm: ``` # sdparm -c WCE /dev/sda /dev/sda: SAMSUNG MZILT3T8HBLS/007 GXA0 # sdparm -g WCE /dev/sda /dev/sda: SAMSUNG MZILT3T8HBLS/007 GXA0 WCE...

@ooptimum you were correct. I had to: ``` # echo 'write through' > /sys/devices/pci0000:00/0000:00:02.0/0000:02:00.0/host0/port-0:0/expander-0:0/port-0:0:0/end_device-0:0:0/target0:0:0/0:0:0:0/scsi_disk/0:0:0:0/cache_type ``` This increased the random 4k write performance to ~150K IOPs. And now fio and iostat...

@ooptimum can you help me with a source to understand why `write back` causes a wareq-sz of 2K?

@mscdex Thanks so much for doing all of that work! I look forward to the libmariadbclient issue getting resolved. Thanks!!!
