This leads to an obvious potential DoS attack. Incoming SYN packets will be allocated too many TCB and the host's kernel memory will be exhausted. In order to avoid this memory depletion, the operating system usually associates a "backlog" queue parameter with the listening interface, which maintains both the upper TCB number of connections and the SYN-RECEIVED state. Although this scheme protects the host's available memory from attack, the backlog queue itself brings a (small) source of attack. When there is no space in the backlog, it is impossible to respond to new connection requests unless the TCB can be recycled or removed from the SYN-RECIEVE state.

④ Thread switching cost is very high. When the operating system switches threads, the context of the thread needs to be preserved and then the system call is executed. If the number of threads is too high, it will not only bring many useless context switches, but also may cause the time for thread switching to be performed to be even longer than the time for thread execution. At this time, the performance is often that the system load is too high and the utilization rate of CPU SY (system CPU) is extremely high, resulting in the system almost falling into an unavailable state.

Code as above; You can see, There are obvious shortcomings, For example, when I click on an element, I need to create a div. I click on the second element to create a div again, We frequently click on such and such elements, and they will frequently create div elements. Although we can remove pop-up codes when we click Close, it is not good for us to frequently create and delete them, especially for performance, and frequent operations on DOM will cause redrawing, etc., thus affecting performance. Therefore, this is a very bad habit. We can now use the monomer mode to realize the pop-up effect. We can instantiate it only once. The following code:
