How I Scaled a C Ingestion Engine from 4M to 209M Rows/Sec: Engineering for the Silicon

The Context: The Invisible Ingestion Wall Most ingestion pipelines fail because they treat data as "text." In high-performance systems, text doesn't exist—only bytes and CPU cycles. While building Forge-Core, I realized that standard fgets or sscanf patterns are a massive "tax" on the CPU. The Bottleneck: Branch Misprediction & Buffer Bloat My early attempts hit a ceiling. Even with multi-threading, I couldn't break 50M Rows/Sec. The profiler (perf) exposed the truth: Instruction Flow Stal...
