slow disk write speed
I'm using Always free and I've created a compute instance with the VM.Standard.A1.Flex shape, and had ubuntu installed. I chose almost all default options. This disk is 50GB.
When I run the command (dd if=/dev/zero of=diskbench bs=1M count=256 conv=fdatasync) to test the write speed, it shows a write speed around 50-70MB/s. Is it normal? I see OCI is using nvme disks so I expect speed should be much faster. Is there anything I need to change?
