I have a fairly comprehensive Meteor app. I find that I need to restart meteor quite often because the build time gradually increases after each code change.
For example, when running with METEOR_PROFILE=100, this is what a code change looks like shortly after running…

Nothing has changed in terms of packages, but it now takes nearly eight times as long to run the _downloadMissingPackages command.
Any idea how I can fix this?
Meteor version: 1.8.0.2
OS: macOS Mojave
Thanks in advance.
