collection when concurrent garbage collection is disabled. It is characterized by frequent recovery to prevent a long period of recovery. The result is that the performance of low memory usage is poor.
Simple Test
The following test results are all on the same computer. The configuration is as follows:
• Windows 7 Ultimate
• Intel Core I3-3220 @ 3.30 GHZ
• 8 GB memory, 3 GB available space
• SQL Server 2014
The program to be tested is ZKEACMS, home p

High performance
There are already many network applications based on workerman, such as multiplayer online games, PHP-Json-Rpc, PHP-Thrift-Rpc, PHP-WebSocket chat rooms, and PHP statistical monitoring systems.
Sample code:

purposes, I still let him run for half an hour and found that he could not display the correct memory usage, after I loaded a large image, his memory line seemed to have only slight fluctuations and remained in the original position. I usually use the memory monitor that comes with the 7210 simulator. The simulation is very accurate, but the only drawback is that the memory is too small to be 200 kb. I have also seen some people use 3220 simulators t

When we buy a computer, the CPU is a key factor to consider because it determines the performance level of the computer. CPU from the early single core, to the current dual-core, multi-core. CPU In addition to the core number, but also the number of threads, the following text to explain the CPU core number of the relationship between the number of thread and the difference. in short, the core number of CPUs is physical, that is, there are several cores on the hardware. For example, a dual cor
