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.

Number of physical CPUs: There are several physical IDs that can be counted without duplicates.

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
