For the ACK part, because the author did not do the detailed textual research, so did not describe. When the PSMP-DTT time is over, the node sends a data frame, such as STA1, to send the upstream data in the PSMP-UTT1, in turn, within its corresponding upstream dispatch cycle. When the Psmp-utt t

Here, I will summarize my development experience and be familiar with kernel device nodes, which is helpful for Kernel-related driver learning and development. 1.

The program is written by PHP a websocket server, the client is connected to send messages continuously, the service side is responsible for responding to requests. Tested: Once per request of client, server PHP consumes time of Microsecs to MICROSECS (message size is different). The server is a single core, 30 clients, using top to view PHP processes occupy CPU around 3-5%, load average 1 minutes load display 0.05 or so. Basically meet expectations.

1. Foreword From the description of the Linux CPU Core power Management (1) _ Overview, kernel CPU control is located in ". \kernel\cpu.c", a connecting module that is responsible for shielding arch-dependent implementation details, Provides the top-level software with a unified API for controlling CPU core (mainly including the implementation of interfaces such

first section CPU utilization and CPU load Under Linux/unix, CPU utilization (CPU utilization) is divided into user state, System State and idle state, respectively, the CPU is in user state execution time, system kernel execution time, and idle system process execution tim

When we use the top command to see the system's resource usage, we see load average, as shown in. It represents the average workload of the system at 1, 5, and 15 minutes. So what is load? How does it relate to CPU utilization?Load average: The system average load is the load of the CPU, which contains information that is not CPU usage, but rather statistics on t

What is the difference between the server CPU and the normal CPU? Below we find a professional literature, quickly to increase knowledge. Overall, there are six main differences between the server CPU and the common computer CPU, so let's look at it together. One, the instruction set is different Home or employment

In Linux, the meaning of CPU load and CPU usage indicates that the Nagios alarm information was viewed yesterday. It was found that the CPU load on one of the servers was too heavy and the machine was CentOS. Information: 2011-2-15 (Tuesday) 17: 50 WARNING-load average: 9.73, 10.67, 10.49There are also alerts sent in the previous two hours: (Tuesday) 16: 50 WARNI

As the name suggests, there is a copy of this variable on each processor.The great advantage of PER-CPU is that access to it requires almost no locks, because each CPU works on its own copy.Tasklet, timer_list and oth

One, the instruction set is different Home or employment computer equipped with the ordinary CPU, usually CISC complex instruction set, the pursuit of instruction set of all-inclusive, as far as possible to integrate a variety of commonly used functions to a piece, but the call speed and hit ratio compared to server CPU lower. The server CPU instruction is typi

Understanding the system structure from the Java perspective serial, follow my Weibo (link) Learn about the latest developments it is well known that the CPU is the brain of the computer, which is responsible for executing the instructions of the program; Memory is responsible for saving data, including the program's own data. As we all know, memory is much slower than CPU. In fact, 30 years ago, the

In electronic technology, the pulse signal is a pulse signal continuously sent at a certain voltage range and at a certain interval. The interval between pulses is called a cycle, and the number of pulses generated per unit time (for example, 1 second) is called a frequency. Frequency is the metering name that describes the number of pulses that appear in a periodic cycle signal (including a pulse signal) per unit time. The standard unit of measurement for a frequency is Hz ). The system clock i
