Are you getting full disk speed from Oracle free tier?

Hey guys I noticed that some people are not getting the full disk IO speed from their oracle free tier. Below is a yabs example by @sh97, im assuming that was set up with the default IOPS option selected in the boot volume, the VPU slider set to 10. But you can select upto 90 or higher in some cases giving a much better disk speed.

Below is VPU set to 10

Increasing Disk Speed When Creating an Instance

When setting up an instance, you can choose the disk speed, for me 90 is the setting that always works (my free tier is in London), ymmv! If i select above 90 sometimes it works and sometimes not.

tick the "specify a custom boot volume size" then change the VPU setting slider for a faster speed disk.

For Those With An Already Running Instance/VPS

For those that have already setup their free tier instances don't worry, you can change the speed while the VPS is running, may need a reboot to take effect. To do this follow these steps.

1. go to your instance main page

2. scroll down and click Boot volume, in Resources

3. then click your instance name under the boot volume heading

4. click edit

5. change the slider to a higher speed then click save.
