## Description If you open the Web IDE for the [GitLab](https://gitlab.com/groups/gitlab-org/gitlab) project you'll see that it takes ~900MB of memory :grimacing:... If you open for a trivially sized project the footprint is ~30MB. https://youtu.be/mNQUVNwZIMk Certainly there's some room for improvement. ## Findings - The GitLab project has ~28,000 files. Using the trivially sized project as a "base memory footprint", we can calculate that **a single file in a repository will take up about 30KB**. This does not include file content (which isn't loaded until the file is actually opened). It's probably that callback functions consume the most memory here... ## Questions - Do files consume more memory than directories?
