🚀 OpenBLD.net is entering a new era of performance

Over the past months, I’ve been working on a major upgrade of the zBLD core.

The focus is clear — acceleration, resilience, and predictable performance under load.

Key improvements:

• Multi-level Rate Limiter (RTL) to absorb traffic spikes
• Thread separation & sharding — reducing pressure on the main processing path
• ~30% of operations moved to async execution
• Stricter RFC-based DoH traffic validation — less “garbage,” lower latency
• Error sampling for unstable clients — reduced disk I/O load
• Reworked domain-filtering engine
• Improved detection of suspicious / DGA domains
• Optimized Linux networking stack and I/O behavior

Result: overall throughput increased by roughly 2×, and priority domains now resolve even faster thanks to smarter deferred analysis.

The update rollout is planned for mid–late December.

Only forward! 💪 Be yourself, be focused!
