Nettet18. jun. 2012 · Low memory continues to be mapped directly into the kernel's address space, and is thus always reachable via a kernel-space pointer. High memory, instead, has no direct kernel mapping. When the kernel needs to work with a page in high memory, it must explicitly set up a special page table to map it into the kernel's address space first. NettetIn this guide, I will try to introduce 9 tips that can be useful for those having old computers with low RAM and want to speed up their system for better performance.

High memory is memory to which the kernel does not have a direct physical address and, thus, it must be mapped via a virtual address. On older 32-bit systems, you will see low memory and high memory due to the way that memory is mapped to a virtual address.

NettetRed Hat Enterprise Linux uses two separate methods for controlling KSM: The ksm service starts and stops the KSM kernel thread. The ksmtuned service controls and tunes the ksm service, dynamically managing same-page merging. ksmtuned starts the ksm service and stops the ksm service if memory sharing is not necessary.

Set the desired value and close the dialog. NettetThe best way to tune a system is to target bottlenecks, or subsystems which limit overall speed. The system specifications can help identify them. If the computer becomes slow when large applications (such as LibreOffice and Firefox) run at the same time, check if the amount of RAM is sufficient.

NettetExtreme values can damage your system. Setting min_free_kbytes to an extremely low value prevents the system from reclaiming memory, which can result in system hangs and OOM-killing processes. However, setting min_free_kbytes too high (for example, to 5–10% of total system memory) causes the system to enter an out-of-memory state …
