Local Build Distribution Server

Internal Tool | Multi-Platform QA Optimization

Implementation

Our QA team consisted of over 40 testers who needed to download and install game builds on their respective consoles multiple times a day. With everyone downloading builds simultaneously from external sources, the network quickly became saturated and frequently collapsed, causing major bottlenecks. Combined with tight testing deadlines, installation times of up to 1 hour per device were severely impacting team productivity and project delivery.

The Solution

I designed and implemented a Local Build Distribution Server to eliminate redundant downloads and optimize network usage. The concept was simple yet highly effective:

  • One designated machine downloads the build once and hosts it locally.

  • That machine acts as a local server, allowing all testers to connect directly through the internal network.

  • Testers can then install builds directly onto their consoles without re-downloading from external sources.

The Challenge

  • Configured a dedicated workstation as a centralized build host.

  • Established secure local network protocols to allow simultaneous access from multiple testers.

  • Adapted the system for multi-platform compatibility, successfully replicating it across PlayStation 4, PlayStation 5, Xbox, Nintendo Switch, and mobile devices.

  • Documented the process to ensure easy onboarding and scalability for the entire QA team.

Results & Impact

  • Reduced installation times from 1 hour to just 15 minutes — a 75% improvement.

  • Eliminated network saturation issues, freeing bandwidth for other critical operations.

  • Boosted overall QA productivity, allowing testers to focus on testing rather than waiting on downloads.

  • Standardized across all platforms, becoming a core part of the team's daily workflow.

  • Scalable solution adopted as a long-term internal practice across multiple projects.

Key Takeaway

  • This project demonstrated how identifying a recurring pain point and applying a simple but well-engineered technical solution can deliver massive operational improvements, directly impacting team efficiency and project delivery timelines.
