       | It _looks_ like the free CI runners have C: drive pointing to a
       | disk that is restored from a snapshot, but often times it hasn 't
       | finished restoring the entire snapshot by the time your workflow
       | runs, so IO can be very slow, even if you don't need to read from
       | the still-frozen parts of the disk. Some software ran inside
       | workflows will do heavy R/W on C: drive, but it's better to move
       | anything that will be written to disk, e.g. caches, to D: if
       | possible. This often leads to much better performance with I/O
       | and more predictable runtimes, particularly when there isn't a
       | lot of actual compute to do.

         | sense that the agent/container tech on Windows would be similar
         | between both AzDO Pipelines and GH Actions. It also makes sense
         | that AzDO Pipelines being "windows-first" for a long time would
         | have better documentation and third-party awareness of the
         | optimizations whereas Windows use on GitHub Actions is much
         | more rare and awareness less evenly spread.
