Merge bitcoin/bitcoin#24707: doc: Speed up functional test runs using ramdisk
17648493df478fa9316cc9ed66fe6bc1c2c820a4 doc: Speed up functional test runs using ramdisk (willcl-ark)
Pull request description:
Using a ramdisk for the functional tests can give noticable speedups for developers and reviewers.
Local testing with an 8GB ramdisk saw a full test run using `test/functional/test_runner.py --jobs=100 --cachedir=/mnt/tmp/cache --tmpdir=/mnt/tmp` reduced from ~280 seconds to ~99 seconds.
Possible bikeshedding opportunity to be had over whether this might best fit into `doc/productivity.md`, but IMO more people will likely see it (and it will therefore be more useful) if it is here.
It seems best to select `tmpfs` over `ramfs` as `ramfs` can grow dynamically (good) but cannot be limited in size and might cause the system to hang if you run out of ram (bad), whereas `tmpfs` is size-limited and will overflow into swap.
