CLI feels much slower than console when getting/setting config values

[wesbillman]

We recently hooked up get/set of config values from the console. They seem to happen almost instantly.

However, when doing the same from CLI there's a noticeable delay in each command.

ftl config set --inline echo.default "coolnewvalue"

If this is in the ftl repo itself it's because the ftl command triggers a rebuild. The slowness is the build.

Would this be true without any changes to the ftl source? Like would we assume even a no-op build would be slow here? Basically, I was just issuing this command over and over without making changes.
