Maximizing Hardware Performance
The OptimizeLab Overlay software repository provides high-performance pre-compiled key applications and function libraries for the AArch64 architecture. It is provided as Launchpad personal package archives (PPAs) and built against Ubuntu 18.04 LTS and Ubuntu 20.04 LTS.
Software packages in the repository are carefully selected and organized to ensure no conflict with the existing software in the system of the corresponding version and continuously track and maintain the security and quality updates. During the development process, we have tried our best to avoid interfering with developers and strive to keep dynamically compiled applications compatible with the original system in most cases after using this repository. In this way, users can safely and smoothly upgrade the Ubuntu LTS version after using the software in the repository.
The repository consists of four components. As the development goes deeper, we will add more components based on user feedback and development plans. You can install repositories as required. However, most of them depend on the base
component.
As the name implies, the base
component is the basis of most other components and is recommended for all users. If this repository is not used, other repositories can still run independently. However, some performance optimization depends on the basic improvement made in this repository. As a result, the optimization effect is not obvious or even no effect is achieved.
To add this repository:
sudo add-apt-repository ppa:optimizelab/optimizelab-base
sudo apt update
The database
component contains a newly compiled database software package. You are advised to use this component when the database is heavily loaded.
To add this repository:
sudo add-apt-repository ppa:optimizelab/optimizelab-database
sudo apt update
The media
component is optimized and upgraded based on some selected media-related software packages. It is recommended for users who have encoding requirements. Some software can also improve the audio and video playback performance. Users who pursue high performance can also use the media
component.
To add this repository:
sudo add-apt-repository ppa:optimizelab/optimizelab-media
sudo apt update
The science
is targeted at the core software package of scientific computing and is mainly used in scenarios such as scientific computing and high-performance computing (HPC). Because it contains a large number of basic computing function libraries, the performance of the science
component is significantly improved in some computing-intensive but non-scientific computing application scenarios.
To add this repository:
sudo add-apt-repository ppa:optimizelab/optimizelab-science
sudo apt update
