[WIP] In the context of embedded router firmware development for the Padavan-NG project, what kernel-level tweaks and low-level system optimizations can be implemented to minimize internet latency without compromising throughput? Ignoring TCP congestion contr...

[Copilot]

• Analyzed existing Padavan-NG codebase and Linux 3.4.113 kernel
• Identified current configuration state (MT7621 SoC, SMP support available)
• Confirmed availability of RPS/XPS, CoDel, fq_codel features
• Found that NET_SCHED is currently disabled (key optimization opportunity)
• Enable and configure advanced QoS/scheduling features for latency optimization
• Implement IRQ affinity and interrupt mitigation optimizations
• Add CPU frequency scaling and power management tweaks
• Enable RPS/XPS network stack parallelization
• Configure NAPI tuning parameters
• Add memory management optimizations for low latency
• Implement kernel preemption improvements
• Add network buffer tuning options
• Create configuration templates for latency-optimized setups
