Distcc Tests

Compilation Benchmarks:

Comparison of build times (Real Time) across different architectures with and without Echse-Net Distcc.

SeaMonkey 2.53.23

LibreOffice 25.2.7.2

Note: Real time represents the actual duration you wait for the build to finish. For i686 architecture, the speedup is massive.

Note: Compilation Time Comparison: Gentoo vs Raspbian (Raspberry Pi) Even though both environments utilized the distcc distributed cluster to accelerate the build process, a massive discrepancy in compilation times was observed. This is a direct consequence of the flags passed during the pre-compilation (configure) stage and the underlying production goals: Gentoo (Full Functionality / Maximum Optimization): The goal was to build a complete, production-ready LibreOffice suite. The package was configured with all features, libraries, and components enabled. Specific architectural optimizations (-march=) recommended by the Gentoo documentation for the particular CPU were applied. This created a monumental demand for RAM, forcing the system into heavy SWAP utilization. Slow disk I/O led to memory thrashing, which drastically inflated the kernel/system execution time (sys). Raspbian (Minimal Version / Demonstration Purpose): This process was purely a proof-of-concept demonstration of cluster capabilities. During the ./configure phase, the codebase was stripped down to its bare bones by disabling every non-essential feature (such as extra languages, specific UIs, and optional modules). Consequently, the total volume of code and dependencies processed by distcc plummeted to an absolute minimum, completely bypassing the RAM and SWAP bottlenecks.

Note: Distributed compilation (distcc) drastically reduces build time from several days to just a few hours by offloading intensive computations to powerful external servers. This solution protects the ARM processor from thermal throttling and prevents RAM exhaustion on the target device.

Distributed distcc Compilation in Action

Note: The video below demonstrates the project build process utilizing the Echse-Net Distcc cluster. Instead of relying solely on the local CPU, compilation jobs for individual source files (.cpp) are securely distributed and processed in parallel by distccd daemons running across paired nodes in the Echse-Net cluster, drastically reducing total build execution times.
