若是尹兄不嫌晦气，可愿与我一道去？愿意奉陪。For example, in the back-end system, There are tabular data, Each piece of data is preceded by a check box button, When you click the check box button, After obtaining the id, it needs to be passed to the server to send an ajax request. The server needs to record this data, To request, if we send an http request to the server every time we click, For the server, the pressure is relatively high and the network requests are frequent. However, if the real-time data of the system is not very high now, we can collect all ID for a period of time (e.g. 2-3 seconds) through a proxy function and send AJAX requests to the server at one time. Relatively speaking, the network requests are reduced and the server pressure is reduced."If the situation develops in this way, it is also to find the weakness of this" killer bee "? As long as we grasp our weaknesses and require our superiors to equip them with more flame throwers, will the situation be much better? Or can you use these 4 74 flamethrowers to attack these "killer bees" more effectively and hold the position more easily than this first encounter with "killer bees"?

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.
