Part V Kernel Tuning

11 Tuning I/O Performance

I/O scheduling controls how input/output operations will be submitted to storage. SUSE Linux Enterprise Desktop offers various I/O algorithms—called elevators— suiting different workloads. Elevators can help to reduce seek operations, can prioritize I/O requests, or make sure, and I/O request is car…

12 Tuning the Task Scheduler

Modern operating systems, such as SUSE® Linux Enterprise Desktop, normally run many different 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…

13 Tuning the Memory Management Subsystem

In order 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.

14 Tuning the Network

The network subsystem is rather complex and its tuning highly depends on the system use scenario and also 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 …
