LLM INFERENCE PERFORMANCE BENCHMARKS

The following table demonstrates the incremental optimization improvements for local LLM inference on consumer RTX hardware:

Change	Tok/s	TTFT (ms)	p95 (ms)	VRAM (GB)	Δ Quality
Baseline FP16	32	350	1200	18.2	0
+ vLLM (paged KV)	54	260	980	16.9	0
+ Q4_K_M	68	250	910	13.1	−1.3%
+ FlashAttn/fused	81	240	820	13.1	−1.3%
+ batched tokenizers/SSE	81	210	620	13.1	−1.3%

Performance Metrics:

• Tok/s: Tokens per second throughput
• TTFT: Time to first token (latency)
• p95: 95th percentile response time
• VRAM: GPU memory usage
• Δ Quality: Accuracy delta vs baseline

This optimization pipeline achieves a 2.5x throughput improvement (32→81 tok/s) while reducing memory usage by 28% and maintaining near-baseline accuracy.
