According to news on June 13, contemporary Intel CPUs actually do not perform as well as they should in the Linux environment, and Intel itself is aware of this, so engineers have been Optimize the performance of Intel CPU under Linux.
Intel recently launched the v2 cluster scheduling patch, claiming that engineers have strengthened the process scheduling level under Linux by developing new cluster scheduling code, which can improve the performance of Intel 12th generation and later CPUs on Linux.

In the 2021 Linux 5.16 version, Intel claimed that there were problems with CPU cluster scheduling. Therefore, the performance of 12th generation Intel processors is reduced under Linux systems.
Intel said that “engineers are currently working on improving the load balancing of the P core and the E core and providing further kernel fixes to ensure that Intel CPUs of the 12th generation and later can perform as they should in Linux. ".
IT House learned from Intel’s report that under the v2 cluster scheduling patch environment, test performance improved by about 1.36%, and multi-threaded workload dropped by 2%. Judging from the current situation, Intel engineers are There is still a long way to go in optimizing scheduling.
The above is the detailed content of Intel develops new scheduling patch for Linux kernel: 12th generation and above CPU performance improved, multi-threaded load reduced. For more information, please follow other related articles on the PHP Chinese website!
NGINX and Apache: Understanding the Key DifferencesApr 26, 2025 am 12:01 AMNGINX and Apache each have their own advantages and disadvantages, and the choice should be based on specific needs. 1.NGINX is suitable for high concurrency scenarios because of its asynchronous non-blocking architecture. 2. Apache is suitable for low-concurrency scenarios that require complex configurations, because of its modular design.
NGINX Unit: Key Features and CapabilitiesApr 25, 2025 am 12:17 AMNGINXUnit is an open source application server that supports multiple programming languages and provides functions such as dynamic configuration, zero downtime updates and built-in load balancing. 1. Dynamic configuration: You can modify the configuration without restarting. 2. Multilingual support: compatible with Python, Go, Java, PHP, etc. 3. Zero downtime update: Supports application updates that do not interrupt services. 4. Built-in load balancing: Requests can be distributed to multiple application instances.
NGINX Unit vs. Other Application ServersApr 24, 2025 am 12:14 AMNGINXUnit is better than ApacheTomcat, Gunicorn and Node.js built-in HTTP servers, suitable for multilingual projects and dynamic configuration requirements. 1) Supports multiple programming languages, 2) Provides dynamic configuration reloading, 3) Built-in load balancing function, suitable for projects that require high scalability and reliability.
NGINX Unit: The Architecture and How It WorksApr 23, 2025 am 12:18 AMNGINXUnit improves application performance and manageability with its modular architecture and dynamic reconfiguration capabilities. 1) Modular design includes master processes, routers and application processes, supporting efficient management and expansion. 2) Dynamic reconfiguration allows seamless update of configuration at runtime, suitable for CI/CD environments. 3) Multilingual support is implemented through dynamic loading of language runtime, improving development flexibility. 4) High performance is achieved through event-driven models and asynchronous I/O, and remains efficient even under high concurrency. 5) Security is improved by isolating application processes and reducing the mutual influence between applications.
Using NGINX Unit: Deploying and Managing ApplicationsApr 22, 2025 am 12:06 AMNGINXUnit can be used to deploy and manage applications in multiple languages. 1) Install NGINXUnit. 2) Configure it to run different types of applications such as Python and PHP. 3) Use its dynamic configuration function for application management. Through these steps, you can efficiently deploy and manage applications and improve project efficiency.
NGINX vs. Apache: A Comparative Analysis of Web ServersApr 21, 2025 am 12:08 AMNGINX is more suitable for handling high concurrent connections, while Apache is more suitable for scenarios where complex configurations and module extensions are required. 1.NGINX is known for its high performance and low resource consumption, and is suitable for high concurrency. 2.Apache is known for its stability and rich module extensions, which are suitable for complex configuration needs.
NGINX Unit's Advantages: Flexibility and PerformanceApr 20, 2025 am 12:07 AMNGINXUnit improves application flexibility and performance with its dynamic configuration and high-performance architecture. 1. Dynamic configuration allows the application configuration to be adjusted without restarting the server. 2. High performance is reflected in event-driven and non-blocking architectures and multi-process models, and can efficiently handle concurrent connections and utilize multi-core CPUs.
NGINX vs. Apache: Performance, Scalability, and EfficiencyApr 19, 2025 am 12:05 AMNGINX and Apache are both powerful web servers, each with unique advantages and disadvantages in terms of performance, scalability and efficiency. 1) NGINX performs well when handling static content and reverse proxying, suitable for high concurrency scenarios. 2) Apache performs better when processing dynamic content and is suitable for projects that require rich module support. The selection of a server should be decided based on project requirements and scenarios.
