![]() Right-click on a process to manage It (Howard Fosdick, CC BY-SA 4.0) It also identifies your motherboard and other computer components.įig. Its Computer -> Summary panel identifies your CPU and tells you about its cores, threads, and speeds. I like HardInfo because its screens are easy to read and it's widely popular. Open source offers several tools for this purpose. To spot a bottleneck, you must first know what hardware you have. Now let's explore how to identify bottlenecks in specific areas. It instantly clues you in on the most common performance problems. For now, check the System Monitor first when your computer slows down. A quick glance tells you immediately whether your processors are swamped, or your computer is out of memory, or you're using up all your internet bandwidth. The Resources panel displays three sections: CPU History, Memory and Swap History, and Network History. Free online course: RHEL Technical Overview.You can identify many performance problems right off. Start it up and click on the Resources tab. Its output is easy to understand, and you can find it in most repositories. Open source offers a plethora of tools to do the job. To identify a bottleneck, you must monitor these six resources. Should any one resource perform poorly, it can create a performance bottleneck. Where to startĪ computer consists of six key hardware resources: My goal is to give you a quick, easy approach that you can use anywhere. ![]() The GUI tools that open source offers make identifying many bottlenecks simple. ![]() They use specialized commands and delve deep into arcane details. Most articles on Linux bottlenecking are pretty complicated. I'll use only open source graphical user interface (GUI) tools to get the job done. Instead, I'll write a follow-up article with performance tweaks. My emphasis is on PCs-I won't cover server-specific bottlenecks in areas such as LAN management or database systems. The techniques apply to both personal computers and servers. This article explains how to identify hardware bottlenecks in Linux systems. Removing a serious bottleneck can make your system fly. ![]() If one component is less capable than the others-if it falls behind and can't keep up-it can hold your entire system back. Computers are integrated systems that only perform as fast as their slowest hardware component. ![]()
