Developer open-sources Optimux, a Go image/video optimizer with a rebuilt worker pool

A developer has open-sourced Optimux, a Go-based service that resizes, re-encodes, and streams images and video on the fly, releasing it under the AGPL-3.0 license. The project had previously run as an internal tool, but is now public primarily because its underlying worker pool design proved technically noteworthy. The developer initially adopted a well-known Go worker pool pattern designed for high-throughput I/O workloads, but profiling revealed it performed poorly for CPU-bound image processing, with nearly 68% of time lost to channel-waiting overhead. After scrapping the original pattern entirely, the developer rebuilt the concurrency model from a synchronous baseline upward, identifying each performance variable in isolation. The reworked approach ultimately surpassed the old pattern's throughput even at its simplest form, highlighting how concurrency design must match the nature of the workload.
