Linux performance Management tools

By |

Just as we’ve provided a series of tips on how to make your Windows 2008 Server run at its utmost maximum efficiency and speed, Monitis has put together advice on making the Linux OS work miracles for you. Our interest is in making your life easier, whether it’s through informational guides such as these or by continually enhancing our monitoring cloudware with cutting-edge services, for example, new monitoring stations around the world and mobile apps for free server monitoring.

In our first post, we offered Linux Server tips on the OS’ features and security set up. You might want to check it out before reading on. In this post, we’re going to discuss tips to improve performance based on Linux’s Configuration, third-party applications that work with the OS and miscellaneous areas.

Keep in mind – as you read through these tips – that you can apply them to get your Linux server to run like a fox – not waddle like a penguin.

Performance Tips for Linux’s Configuration:

Here are some regular ways to get the best performance out of your Linux Server by making updates in its configuration.

9. Updating Default Kernel Parameter Settings:

To run enterprise applications smoothly and successfully, such as a database server on Linux distribution, it is required to update some of the default kernel parameter settings. For example, the 2.4.x series kernel message queue parameter “msgmni” has a default value (for example, shared memory, or shmmax is only 33, 554, 432 bytes on Red Hat Linux by default), and that allows only a limited number of simultaneous connections to a database. Mentioned below are some recommended values (by the IBM DB2 Support Web site) for database servers to run optimally:

  1. kernel.shmmax=268435456 for 32-bit
  2. kernel.shmmax= for 64-bit
  3. kernel.msgmni=1024
  4. fs.file-max=8192
  5. kernel.sem=”250 320″

10. Tune Up Your TCP

Tuning the TCP protocol helps to improve network throughput for connection-hungry applications. Larger TCP Linux sizes are recommended for communications across wide-area networks with large bandwidth and long delay characteristics – in order to improve data transfer rates. The TCP Linux size determines how much data that a sending host can transmit to a receiving host, without receiving an acknowledgment of data transfer.
