In the new TOS 6 system, the latest 6.1 kernel is adopted, while the previous system (TOS 5/5.1) used the 5.15 version kernel. Over the past few years, with the continuous evolution of the Linux kernel, from version 5.15 to the latest 6.1 LTS version released in December 2022, there have been many iterations of updates, including 5.16, 5.17, 5.18, 5.19, and 6.0. Compared to the earlier 5.15 version, the 6.1 version kernel has hundreds of optimizations and new features, making the kernel performance stronger and more stable. Some updates are even more urgently needed for business users. Therefore, upgrading to a new kernel is necessary to achieve better performance, stability, and security.
What are the important improvements in the 6.1 kernel?
Here are some major improvements in the 6.1 kernel:
- Scheduling program optimization: The 6.1 kernel has optimized the scheduling program, including improved fair scheduling algorithms and more intelligent CPU scheduling strategies to improve the performance and response speed of multi-core processors.
- Memory management improvement: The 6.1 kernel adds new memory management features, including support for transparent huge pages, to improve memory allocation and release performance. Additionally, it has improved memory compression and cache management to increase memory usage efficiency.
- File system enhancement: The 6.1 kernel adds support for new file systems, including improved ext4, as well as XFS and Btrfs performance optimizations. These improvements provide better file read-write performance and data processing capabilities.
- Network performance improvement: The 6.1 kernel has improved the network stack, including optimizations to TCP/IP protocols and new algorithms to enhance network performance. Additionally, it adds support for multipath TCP connections to increase network connection reliability and performance.
- Enhanced security: The 6.1 kernel adds new security features, including an improved mandatory access control (MAC) framework and stronger kernel self-protection mechanisms to enhance system security. Additionally, it adds support for encrypted file systems to protect the confidentiality and integrity of data.
- Power management improvement: The 6.1 kernel adds new power management features, including optimizations to processor power consumption and new algorithms, to extend battery life and improve system performance. Additionally, it improves system sleep and wake-up functions to increase response speed.
- Virtualization support enhancement: The 6.1 kernel adds support for virtualization technologies, including optimizations to virtual machine monitors (VMMs) and new features to improve virtual machine performance and security. Additionally, it improves support for containerization technologies to provide better isolation and security.
Which TNAS models are compatible with the new 6.1 kernel?
Due to hardware platform restrictions, TNAS models based on ARM hardware platforms cannot use the 6.1 kernel. Therefore, TNAS models that are compatible with the new 6.1 kernel are those based on the x86 hardware platform.
