Source code mounts not using cached consistency, Yarn extremely slow

When running yarn install inside the default node (LTS) container, it takes a long time to run.

I noticed that too, using cached consistency helped, not sure it resolved everything though

@Chuxel this would be a good addition to the tips and tricks section. The other way to speed this up is to create a volume and then do development inside the volume.

@egamma The is one of the reasons we added workspaceMount. Unfortunately it is waiting on #442 for a full fix since you need to use an absolute path. I also wonder if we shouldn't use cached for the default mount.

@egamma I forgot to mention that the cached consistency link above is from our docs... I could add something into tips and tricks that references it, but I think we should consider these +1s for #442 as well along with considering using cached by default.

yes I guess making it the default would save you from a lot of requests from people not reading the docs. Also as soon as a project is large enough it really the only viable option. At the moment it makes using docker compose pretty mandatory.

I would fix #442 with high priority though, docker might improve options on various operating system (maybe a tmpfs option will one day surface on windows, just guessing). You don't want people to be unable to harness future docker improvements by locking things done too much.

The specifics of this issue was actually resolved a while ago. There's the ability to pick the mount consistency as a property along with tips for using volume mounts to speed things up or using Open Repo in Container which uses a volume. Thanks!
