Apex Network Optimizer - Update v1.6.0 (The Asynchronous Engine)

This massive update introduces the Asynchronous Pipeline Architecture alongside Hybrid LZMA2 Support. We have completely rewritten how packets flow through the Netty pipeline, allowing tiny critical packets to bypass heavy chunk compression, resolving all client-side stuttering and server-side timeouts.

🚀 Asynchronous Pipeline Architecture

• Zero Head-of-Line Blocking: Completely refactored the ApexCompressor and ApexDecompressor. Heavy packet processing no longer queues up in a single Netty EventExecutorGroup. Instead, massive chunks are detoured into a global parallel ForkJoinPool while normal traffic instantly leap-frogs them.
• Perfect Interaction Latency: Because small packets instantly pass through the pipeline undisturbed, real-time interactions (like swinging a sword or using items) are now perfectly crisp, even while downloading gigabytes of LZMA2 chunk data in the background.
• KeepAlive Immunity: Fixed severe ping spikes and "Moved too quickly!" desyncs. KeepAlive packets now process perfectly on time, completely immune to the stutter and stalls that previously plagued bulk chunk transfers.

⚙️ Hybrid LZMA2 Compression Stack

• Integrated LZMA2 Encoder: Officially integrated the industry-leading LZMA2 algorithm alongside Zstd. You can now use ZSTD, LZMA2, or HYBRID modes in the server config.
• Intelligent Hybrid Mode: In Hybrid mode, Apex automatically inspects outgoing packets. Small packets (like entity movement) are compressed instantly with Zstd, while massive chunk packets are intercepted and crushed down further using LZMA2.
• Unprecedented Compression Ratios: Players with any internet type can now achieve up to a 10.0x reduction in bandwidth (nearly 90% savings), utterly obliterating connection bottlenecks.

🛠️ Quality of Life & Configuration

• Automatic Dictionary Synchronization: You will never need to manually download or distribute the minecraft_nbt.dict file again! The server now instantly detects missing or outdated client dictionaries during login and beams down the latest 110KB file in 32KB chunks. The client automatically reassembles, verifies, caches, and hot-reloads it without requiring a game restart!
• Live Hybrid Tuning: The /apex level <level> command now intimately understands your active compression stack. It seamlessly manages Zstd (1-22 bounds) and LZMA2 (0-9 bounds) limits dynamically, applying the changes live without a server reboot.
• Backpressure Priority Fix: Fixed a flow-control flaw where HIGH priority packets could permanently starve the download queue out of bandwidth tokens, stalling the game. Strict starvation limits have been removed, smoothing out burst traffic.
• Cleaned Pipeline: Removed obsolete legacy Netty worker groups from the pipeline injector to make room for the new ForkJoin adapters. The pipeline is now leaner and infinitely more scalable across high core-count CPUs.

📈 What to Expect

• Butter-Smooth Gameplay: Zero Netty thread stalls mean that massive modpacks no longer choke your client's interaction capability when flying into new zones.
• Lower Data Usage: For users on limited or throttled connections, the addition of LZMA2 chunk crushing shrinks the game's data footprint to practically nothing.
