Second and final phase of the 2025 improvements is now done.
I worked through the 18 improvements identified in my blog’s health check report, turning it into a more efficient and reliable static site generator. This included performance enhancements such as chunked file reading with 8KB chunks to prevent memory issues, concurrent processing with a ThreadPoolExecutor using 4 workers, and a markdown caching system that stores 604 posts for faster rebuilds. I also reduced storage needs by converting images to WebP and using batch processing, bringing the size down from 8.5MB to 2.14MB. Other updates included retry logic and connection pooling for network stability, progress bars for user feedback, and additional logging options with verbose and debug modes.
These changes brought the build times down by 41%, from 11.53 seconds to 6.82 seconds, while keeping everything compatible with existing workflows. I also improved the codebase by adding type hints, removing duplicate code, and creating utility scripts for image handling and progress tracking. The deployment system now has retry mechanisms for temporary failures and more efficient CloudFront configurations with specific path invalidations.
Overall, the updates make the blog faster, more efficient, and easier to maintain, while keeping the original functionality intact. Each change was implemented with the goal of making the system more dependable and user-friendly for long-term use.
