Part V Kernel tuning

  • 12 Tuning I/O performance
  • I/O scheduling controls how input/output operations will be submitted to storage. openSUSE Leap offers various I/O algorithms—called elevators—suiting different workloads. Elevators can help to reduce seek operations and can prioritize I/O requests.

  • 13 Tuning the task scheduler
  • Modern operating systems, such as openSUSE® Leap, normally run many tasks at the same time. For example, you can be searching in a text file while receiving an e-mail and copying a big file to an external hard disk. These simple tasks require many additional processes to be run by the system. To pro…

  • 14 Tuning the memory management subsystem
  • To understand and tune the memory management behavior of the kernel, it is important to first have an overview of how it works and cooperates with other subsystems.

  • 15 Tuning the network
  • The network subsystem is complex and its tuning highly depends on the system use scenario and on external factors such as software clients or hardware components (switches, routers, or gateways) in your network. The Linux kernel aims more at reliability and low latency than low overhead and high thr…

  • 16 Tuning SUSE Linux Enterprise for SAP
  • This chapter presents information about preparing and tuning openSUSE Leap to work optimally with SAP applications with sapconf. sapconf is for SUSE Linux Enterprise systems that install SAP applications. Customers who have SUSE Linux Enterprise Server for SAP Applications should use saptune.
