Could you build this?
No Achieving 1.4 GB/s log analysis requires low-level AVX2 SIMD intrinsics, vectorization, and cache-aware memory layout that AI assistants cannot reliably write or optimize.
What it would actually take: The tool relies on C/C++ or Rust leveraging x86 AVX2/AVX-512 SIMD vector intrinsics for vectorized string search, branchless parsing, memory-mapped I/O (mmap), and parallel chunking across CPU cores. The difficult part is maximizing CPU pipeline throughput, avoiding cache misses, and writing hand-tuned assembly or SIMD algorithms for multi-byte pattern matching. It requires specialized systems performance engineering and microarchitecture expertise.

Same idea, different domain
Nobody's really built a analytics & bi tool for Legal yet.
