Tuning the system is not only about optimizing the kernel or getting the most out of
your application, it begins with setting up a lean and fast system. The way you set up
your partitions and file systems can influence the server's speed. The number of active
services and the way routine tasks are scheduled also affects performance.
9.1 Planning the Installation
A carefully planned installation ensures that the system is basically set up exactly as
you need it for the given purpose. It also saves considerable time when fine tuning the
system. All changes suggested in this section can be made in the Installation Settings
step during the installation. See Section“Installation Settings” (Chapter6, Installation
with YaST, ↑Deployment Guide) for details.
9.1.1 Partitioning
Depending on the server's range of applications and the hardware layout, the partition-
ing scheme can influence the machine's performance (although to a lesser extend on-
ly). It is beyond the scope of this manual to suggest different partition schemes for
particular workloads, however, the following rules will positively affect performance.
Of course they do not apply when using an external storage system.
• Make sure there always is some free space available on the disk, since a full disk
has got inferior performance
• Disperse simultaneous read and write access onto different disks by, for example:
