I executed a full permutation matrix using Lucene's JMH suite (`PostingVsDocValuesFacetBenchmark.java`) across **1 Million**, **10 Million**, **100 Million**, and **1 Billion** documents at $1\%$ and $10\%$ match densities, and category counts $K = 5$ and $K = 10$. ### Throughput Matrix (Ops / Second & Speedup Ratio) | Index Size ($N$) | Match Density | Matching Docs | Categories ($K$) | Traditional DocValues | Single-Pass Posting-Based | **Throughput Gain / Speedup** | | :---: | :---: | :---: | :---: | :---: | :---: | :---: | | **1 Billion** | **10%** | **100,000,000** | **5** | 2.508 ops/s | **11.085 ops/s** | 🚀 **+341.9% (4.42x FASTER)** | | **1 Billion** | **10%** | **100,000,000** | **10** | 2.434 ops/s | **5.561 ops/s** | 🚀 **+128.5% (2.28x FASTER)** | | **1 Billion** | **1%** | **10,000,000** | **5** | 3.783 ops/s | **11.141 ops/s** | 🚀 **+194.5% (2.94x FASTER)** | | **1 Billion** | **1%** | **10,000,000** | **10** | 3.778 ops/s | **5.453 ops/s** | 🚀 **+44.3% (1.44x FASTER)** | | **100 Million** | **10%** | **10,000,000** | **5** | 22.596 ops/s | **111.297 ops/s** | 🚀 **+392.5% (4.93x FASTER)** | | **100 Million** | **10%** | **10,000,000** | **10** | 23.696 ops/s | **55.912 ops/s** | 🚀 **+135.9% (2.36x FASTER)** | | **100 Million** | **1%** | **1,000,000** | **5** | 36.262 ops/s | **75.740 ops/s** | 🚀 **+108.8% (2.08x FASTER)** | | **100 Million** | **1%** | **1,000,000** | **10** | 37.857 ops/s | **54.634 ops/s** | 🚀 **+44.3% (1.44x FASTER)** | | **10 Million** | **10%** | **1,000,000** | **5** | 250.516 ops/s | **1,241.972 ops/s** | 🚀 **+395.7% (4.96x FASTER)** | | **10 Million** | **10%** | **1,000,000** | **10** | 251.795 ops/s | **617.005 ops/s** | 🚀 **+145.0% (2.45x FASTER)** | | **10 Million** | **1%** | **100,000** | **5** | 406.054 ops/s | **1,274.608 ops/s** | 🚀 **+213.9% (3.14x FASTER)** | | **10 Million** | **1%** | **100,000** | **10** | 391.367 ops/s | **580.738 ops/s** | 🚀 **+48.4% (1.48x FASTER)** | | **1 Million** | **10%** | **100,000** | **5** | 2,524.309 ops/s | **16,441.163 ops/s** | 🚀 **+551.3% (6.51x FASTER)** | | **1 Million** | **10%** | **100,000** | **10** | 2,672.635 ops/s | **8,091.425 ops/s** | 🚀 **+202.7% (3.02x FASTER)** | | **1 Million** | **1%** | **10,000** | **5** | 8,338.912 ops/s | **14,392.758 ops/s** | 🚀 **+72.6% (1.73x FASTER)** | | **1 Million** | **1%** | **10,000** | **10** | 8,711.087 ops/s | 8,174.646 ops/s | -6.1% (DocValues optimal for low matches, $K=10$) | Also, attaching the micro-benchmark JMH file if any contributor wishes to analyse further.
