Fine-Tuning Flussonic Media Server and the Operating System. This section describes certain common issues and techniques of tweaking the operating system and Flussonic Media Server software for working under high load. UDP capture setup. For ingesting UDP multicast streams, you'll need to increase the amount of memory allocated to UDP buffers. There are several parameters and criteria available to tune the Linux kernel according with specific application requirements. Tuning Linux kernel is a challenging task specially because it requires in-depth understanding of the hardware, operating system, and application.

In this chapter, we will discuss in detail about the system performance in Unix.
We will introduce you to a few free tools that are available to monitor and manage performance on Unix systems. These tools also provide guidelines on how to diagnose and fix performance problems in the Unix environment.
Unix has following major resource types that need to be monitored and tuned −
CPU
Memory
Disk space
Communications lines
I/O Time
Network Time
Applications programs
Performance Components
The following table lists out five major components which take up the system time −
| Sr.No. | Component & Description |
|---|---|
| 1 | User State CPU The actual amount of time the CPU spends running the users’ program in the user state. It includes the time spent executing library calls, but does not include the time spent in the kernel on its behalf |
| 2 | System State CPU This is the amount of time the CPU spends in the system state on behalf of this program. All I/O routines require kernel services. The programmer can affect this value by blocking I/O transfers |
| 3 | I/O Time and Network Time This is the amount of time spent moving data and servicing I/O requests |
| 4 | Virtual Memory Performance This includes context switching and swapping |
| 5 | Application Program Time spent running other programs - when the system is not servicing this application because another application currently has the CPU |
Performance Tools
Unix provides following important tools to measure and fine tune Unix system performance −
| Sr.No. | Command & Description |
|---|---|
| 1 | nice/renice Runs a program with modified scheduling priority |
| 2 | netstat Prints network connections, routing tables, interface statistics, masquerade connections, and multicast memberships |
| 3 | time Helps time a simple command or give resource usage |
| 4 | uptime This is System Load Average |
| 5 | ps Reports a snapshot of the current processes |
| 6 | vmstat Reports virtual memory statistics |
| 7 | gprof Displays call graph profile data |
| 8 | prof Facilitates Process Profiling |
| 9 | top Displays system tasks |
You can use Manpage Help to check complete syntax for each command mentioned here.
Huawei announced a server operating system, openEuler at the 4th Huawei Conference in Shanghai On September 19 last year. Huawei also revealed that Huawei is preparing open source communities with companies such as Red Flag and Wuhan Shenzhidu at the same time.
Huawei will gradually open up its technology accumulation in the field of ICT basic software, and open source the basic platform capabilities in the operating system, compiler / JDK and other fields to the openEuler community.
In the openEuler community, users can download operating system installation images or source code, quickly understand and learn the implementation of the openEuler OS.
The openEuler has two open-source sub-projects: A-Tune and iSula: A-Tune is an intelligent performance optimization system software and iSula is a cloud-native solution that can meet the multiple needs of the ICT field.
Developers can access the following links to obtain relevant code and documents for reference and learning, and to understand the architecture and source code of the openEuler operating system.
EulerOS is one of the best-operating systems currently supporting TaiShan servers. It has strong competitiveness in terms of performance, compatibility, and power consumption.
- Improve multi-core concurrency and enhance business performance; L2 Cache sharing technology to improve access efficiency between different OSD processes; for the first time, a kernel patch is implemented in Kunpeng processor architecture.
- By enabling the key features of the Kunpeng processor, it has achieved performance breakthroughs in core business scenarios and has continued to contribute to the open-source communities such as Linux kernel, virtualization, GCC, OpenJDK, and Docker.
Also the company has announced that Huawei’s database GaussDB will also be open-source, which currently covers 70% of enterprise business scenarios, and will be fully online before June 30, 2020.
