GitHub's Project Cyclops was launched in response to performance issues experienced by some of its largest monorepo customers, particularly during push operations. The initiative involved collaboration across various GitHub engineering teams and the implementation of multiple strategies to enhance monorepo push performance. These strategies included optimizing repository maintenance processes, making the `git repack` operation faster, and removing an artificial limit on push operations on file servers. Additionally, GitHub improved its system by precomputing checksums to reduce lock times during updates. As a result, push errors were significantly reduced, enhancing the overall user experience, especially for customers with large monorepos. The project's success also led to improved performance for all GitHub users and provided a scalable architecture with ample capacity for future growth. GitHub's efforts were supported by feedback and collaboration from its monorepo customers, who played a critical role in identifying and resolving issues.
