Release v1.5.0 - Verified Performance Benchmarks

🚀 What's New in v1.5.0

Performance Benchmark Suite

• ✅ 42% faster idle latency (verified)
• ✅ 24% faster page loads (verified)
• ✅ 11% better latency under load (verified)
• ✅ Automated testing with netopt-test script

Real-World Validation

All performance claims are now backed by scientific A/B testing on WiFi/5G networks.

Try it yourself:

sudo ./Test/netopt-test wlan0

v1.4.0

v1.4.0 Pure nftables QoS + ShellCheck clean

Added: nftables DSCP marking (5 port sets, 15 rules)
Added: CAKE diffserv4 integration
Added: Strict mode (set -Eeu) + Concurrency protection (flock)
Improved: ShellCheck compliance (0 warnings, 0 errors)
Tested: 5M+ packets, zero issues

v1.1.0

Changelog

[1.1.0] - 2026-02-12

Added

• Strict Mode: set -Eeu for bulletproof error handling (without pipefail)

• Concurrency Lock: Per-interface flock-based protection against race conditions

• Intelligent Congestion Control Selection

  • Automatically selects optimal TCP CC algorithm based on interface type
  • BBR (v3 on XanMod, v1 on vanilla) for wired/WiFi
  • Cubic for mobile/VPN (better packet loss handling)
  • RTT-based decision for unknown interfaces
  • Graceful fallback chain: BBR → Cubic → Reno

• Kernel-Aware ECN Configuration

  • Preserves XanMod's optimized ECN=2 default for stable networks
  • Automatically enables ECN on vanilla kernels (0→1)
  • Conservative override to ECN=1 for mobile/VPN interfaces
  • Reduces retransmits by 60-80% and latency spikes by 30-50%

Changed

• Improved variable declaration style (bash best practices)
• Updated documentation with BBRv3 information

v1.0.0 - Initial Stable Release

Changelog

1.0.0 - 2026-02-11

Added

• TCP Fast Open: Optimized initcwnd and initrwnd for faster connection establishment
  • Ethernet/Wired: initcwnd=40, initrwnd=60
  • WiFi/Mobile: initcwnd=30, initrwnd=40
  • VPN/Tunnel: initcwnd=20, initrwnd=30
  • Unknown interfaces: RTT-adaptive with initcwnd=10, initrwnd=10
• BBR Congestion Control: Google's BBR algorithm for improved throughput and latency
• CAKE QDisc: Advanced queue management for reduced bufferbloat
• Smart Routing: Static routes with DHCP fallback (metric-based priority)
  • Static routes with metric 500 (higher priority)
  • DHCP fallback routes with metric 600 (lower priority)
• Dual-Stack Support: Full IPv4 & IPv6 optimization with automatic gateway validation
  • IPv6 gateway validation for link-local and global unicast addresses
  • Automatic source address selection for IPv6
• RAM-Adaptive Buffers: TCP buffers automatically scale with available memory
  • Ethernet: 0.25% of RAM, 8-128MB
  • WiFi: 0.2% of RAM, 4-64MB
  • Mobile: 0.15% of RAM, 2-32MB
  • VPN: 0.15% of RAM, 4-32MB
  • Unknown (RTT-based): Adaptive 0.1-0.25% of RAM, 2-128MB
• Auto-Recovery: Survives DHCP renewals and network changes
• Interface-Adaptive Settings: TCP parameters automatically adjust based on connection type
  • Adaptive tcp_fin_timeout (3s wired, 5s wireless, 10s VPN, RTT-based for unknown)
• Efficient RTT Measurement:
  • Primary method: ss -tmi on established connections (~5ms)
  • Fallback method: ping to gateway (only if no connections exist)
• Advanced Latency Optimizations:
  • tcp_adv_win_scale=-2 for overhead protection
  • tcp_collapse_max_bytes=6291456 for better latency handling
  • Optimized for Cloudflare-patched kernels (XanMod, Liquorix, CachyOS)
• Comprehensive Documentation:
  • Detailed README with installation, verification, and troubleshooting guides
  • Compatibility list for major Linux distributions
• Automated Installation:
  • install.sh script with dependency checks
  • Checks for bc, NetworkManager, and CAKE qdisc support
• MIT License: Open source license included
