Advanced Memory Management

Nitrux focuses on optimizing performance and responsiveness by implementing advanced memory management tweaks.

• Reduced memory compaction overhead. Reduced CPU overhead and improved overall system responsiveness, especially in memory-intensive applications, leading to more stable performance by avoiding sudden spikes in CPU usage caused by proactive compaction.
• Improve performance in contended lock scenarios. By allowing more aggressive page locking, we improve performance in scenarios with memory page contention, which can occur in applications with high memory usage and multi-threaded environments.
• Panic prevention (OOM Killer). Instead of freezing the entire system when memory runs out, we configure the kernel to kill only the specific task causing the shortage surgically.
• Enable THP (Transparent Hugepages) for all memory locations. This change will improve performance for applications with considerable memory usage and access patterns that benefit from larger pages.
• Disable memory page fragmentation. In workloads like gaming, this change can provide benefits such as reduced CPU overhead, improved system responsiveness, and more predictable performance.
• Improve system memory stability. We significantly increased the memory map limit to 16 million, preventing crashes under heavy workloads, such as Star Citizen, Elasticsearch, and certain Wine/Proton games that require many memory mappings.
• Handle sudden allocation reserves. We reserve a dedicated block of RAM for atomic operations, ensuring the system can handle bursts of network traffic or hardware interrupts without stuttering.
