Hi,
pwrite is fast, thoug it's async and it takes ~12s to flush:
time /usr/sbin/xfs_io -f -c "pwrite 0 4568293535"
/ceph/grid/cacheslow/data/aa/007494abc70353384e4788624d19fe268db8ce
wrote 4568293535/4568293535 bytes at offset 0
4.255 GiB, 1115307 ops; 0:00:04.39 (992.045 MiB/sec and 253963.64
Thanks a lot, I will give it a try, I plan to use that in a very
controlled environment anyway.
Best regards,
Andrej
