Background: The business system, running in Windows version, is deployed locally and consumes approximately 5% of CPU resources. The Linux version of the business system, deployed within a VMware-installed CentOS8 environment, exhibits abnormal resource consumption. Problem Description Host Machine: Windows 10 Enterprise VMware: 17.5 Virtual Machine: CentOS8 The virtual machine resource allocation is 4C8GB, running the business system. The business system is deployed in the Linux system within the virtual machine, and the internal top command observes system resource usage.

In software development and operations, deadlocked processes are frequently encountered. This situation can lead to performance degradation or service unavailability. This article introduces how to use the pstack tool to troubleshoot deadlocked process issues by analyzing process stack information to identify the root cause and resolve it. Background: A child service within the risk control system experienced a deadlocked state, resulting in the unavailability of the risk control service. Due to the lack of service availability monitoring, the deadlocked process situation was not detected in a timely manner, leading to system unavailability.

Designed a行情 SDK, implementing different callback function implementations, and performed an extensive test. Recently I’ve been looking into C++ function programming, where functions have become first-class citizens, flowing within the program internally – what’s the difference in performance?

Previous article link: Compiler, Callback Functions, Performance Testing leimao大佬 also did similar tests, so I borrowed their code.

Suddenly, I was feeling the urge to browse for new wallpapers, sticking with my usual black series, with some areas colored in, and the desktop needing to display icons. Other color schemes would result in blurry icons. I stared at the assembly code, trying to figure it out, but couldn’t understand it. I tried throwing it to an AI, explaining the instructions, but it failed to explain the context – clearly, this was a command used for a specific scenario.

Recently, someone asked how to download Focus Interview videos. My mind immediately went to the usual – eight or nine out of ten times it’s encrypted using an m3u8 method, and a bit of simple processing is all it takes. Downloader https://github.com/nilaoda/N_m3u8DL-CLI m3u8 downloader is an open-source command-line m3u8/HLS/dash downloader that supports ordinary AES-128-CBC decryption, multi-threading, custom request headers, etc. Supports Simplified Chinese, Traditional Chinese and English.

The company adjusted its security policies. Ultimately, ‘Mechanical Mini’ was relocated back home as a backup server, along with a full system reinstallation. Ubuntu switched to Windows Server; due to an irregular activation method – used at home – it seemed like it wouldn’t be activated, and that was fine. An unconventional activation triggered Mi

Windows platform has RuMaster (Entertainment Master), which isn’t known for highly accurate data, but it’s still useful as a reference. Of course, there are other professional benchmarking software options available. When it comes to Linux systems, there haven’t seemed to be any particularly suitable benchmarking software found. Sysbench is a versatile benchmark testing tool that can be used to test CPU, memory, file I/O, thread performance, and more. You can use Sysbench to execute various performance testing tasks.
