According to my project practice, there are mainly several key points:
1: Static tree support, that is, all the data loaded to the client at a one-time.2: Asynchronous tree, that is, only one level or several levels of nodes are loaded at a time, and child nodes can load data asynchronously.The 3:checkbox tree (possibly a static tree or an asynchronous tree) is used to select (such as selecting an organization, selecting a data dictionary item), and so on, preferably to support node cascade (Th
performance may be somewhat inadequate. But it should be enough in practice. Here are some test data, using Php5.5.6,redis 2.8:
21000 set/seconds key and value both use the size
21000 get/seconds
use _keys *_ command can query to 30,000 keys in 0.130 seconds
Similar extensions to Predis are: Phpredis, an extension written in C. The test performance results are as follows:

29400 get/seconds

Vswitches are still commonly used, so I have studied some questions about vswitch password cracking. I will share them with you here, hoping they will be useful to you. As we all know, both vswitches and vrouters require certain security guarantees. That is to say, we need to configure a reasonable password for them in a timely manner. What should we do if this password is forgotten? I have met this time. Due to job transfer, the former network administrator left the department, but set a passwo

Many enterprises now have their own Metro Ethernet services. Here we will give you an analysis of the coexistence of Metro Ethernet and traditional WAN services, South Korea's Enterprise Networks Company (formerly GNG Networks) an Optical Transport MAN (MAN) is being built along the subway lines in six major South Korean cities (including Seoul) and plans to provide Metro Ethernet services for enterprises. Enterprise Networks uses the Cisco 15454 Optical Transport Platform.
