- 12 Tuning I/O Performance
I/O scheduling controls how input/output operations will be submitted to storage. SUSE Linux Enterprise Server 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 SUSE® Linux Enterprise Server, 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…
- 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…
