Every context switch costs time. Every branch change hits your flow. For large repos, git checkout can take seconds or even minutes. Multiply that across dozens of switches per day, per engineer, and the total hours lost each sprint become real money.
Teams often ignore this friction because Git feels “fast enough.” But on active projects, checkout delays pile up alongside dependency installs, build steps, and environment syncs. Slow checkouts block code reviews, feature work, and bug fixes. They also discourage testing changes across multiple branches, which can lower quality.
Engineering hours saved from faster checkouts are not theoretical. If git checkout takes 8 seconds on average, and each engineer switches branches 15 times a day, that’s 2 minutes wasted daily per person. Across a 20-engineer team, that’s 40 minutes burned every day—3+ hours each week—just waiting for Git. Optimize that, and you reclaim full working days every quarter.
