Consistent monitoring of hardware resource-utilization and performance of different processes help you figure out and improve bad performing areas of your Linux environment.
Linux is one of the most popular operating system in the public server domain and the enterprise environments where the security, performance, robustness, cost, and reliability matters a lot. Linux is an open source operating system that was developed back in 1991 and released under general public license GNU. Since its first release, many different versions and its replica have been developed. The major operating systems that are based on Linux platform include Android, Debian, Ubuntu, CentOS and others. Linux leads the server market with over 36.72% share followed by different versions of Unix OS. A whopping share of 97% in supercomputer market is held by Linux operating system. The mainframe market share of Linux OS stands at about 28%; while in the desktop and laptop market, Linux has a very low share of about 1.34%. More than 54% of smart phone and other handheld devices run on Android, which is a derivative of Linux OS.
In an industry grade environment, the performance of Linux operating systems matter a lot because Linux machines are responsible for handling many mission critical processes that directly impact the revenue, reputation and business survival of the companies. You can improve the performance of your Linux environment through different activities such as:
- Proper monitoring & correcting of server parameters
- Optimizing server configurations
- Optimizing third party applications’ configurations
In this article, we are going to discuss about some major tips that are handy in improving the performance of Linux environment; a few of those major tips are listed below.
- Consistent Monitoring
It is the first and most important thing to monitor the performance of your Linux environment on a regular basis to track any kind of issues or under-performance of different processes and parameters. A few very important commands such as sar, vmstat, free, iostat, top and others are very useful to manually check the parameters of server performance on a regular basis. The checking of performance of your Linux server can also be done through a cloud based sever monitoring service. SiteObservers is one of the best such server monitoring service option available in the marketplace.
- Turn-off Unnecessary Services
Linux operating system comes with numerous features, capabilities and services that are not used by everyone; therefore, it is very important to turn off those services that are not in use such as Xfs, Autofs, Apmd, Sendmail and others. By turning off unnecessary services, you can save a lot of RAM and CPU utilization, and subsequently can improve server performance considerably.
- Disable Unused Modules and Control Panels
Linux server environment supports multiple cloud based control panels, and different modules such as FrontPage support and others. Disable all unnecessary modules and control panels such as Plest, Cpanel and others. You can also enable them when they are required via very simple step by step procedures. By disabling control panels and other software modules, you can improve RAM utilization as much as about 30% or even more.
- Keep System Updated
It is highly recommended to keep Linux kernel parameters as well as other software up to date to enhance the performance of your Linux environment. Always customize the default parameters of Linux OS as per the requirements of your own environment; thus, you can improve server performance substantially. Meanwhile, always keep implementing the newly released patches available in the marketplace to boost the system performance.
- Tuning of Network Functions
Linux environment supports both IPV4 and IPV6 versions and other features related to the network performance. If you are not using IPV6 then disable it and also tune up the transmission control protocol TCP to improve network performance, which will, subsequently improve overall performance of your OS environment. You can set larger TCP data size for that purpose.
- Appropriate Apache Configuration
It is very critical to configure Apache and other such modules properly to improve the performance of the Linux environment. Make sure that Apache is using the proper volume of memory; you can save RAM up to 40%, if you properly configure Apache according to the “MinSpareServers” & “StartServers” directives. You can also regularly keep Apache performance under monitoring, and make desired changes in configurations that improve the performance.
- Proper MySQL Configuration
Databases are very fundamental components of an entire Linux or other OS environments; a proper allocation of server resources can improve the performance of whole Linux environment. It is very important to allocate adequate memory cache size for MySQL to make sure no bogging down of database at larger requests takes place. You can also decrease the cache size, if not required.
Other than above mentioned main tips, you can improve the performance of Linux environment by many other small/big activities such as, tuning up virtualbox, disabling GUI, optimizing cache directories, over-clocking the memory, optimizing boot speed, reducing system logging activities and others.
To have a clearer and deeper perspective on your Linux environment, you can use enterprise level monitoring service to monitor the Linux and related software’s performance. To learn more about the enterprise grade free cloud based Linux monitoring service click here.
