188555 what does the housekeeper mean by the flow cc inside?

CC stands for flowing liquid flow unit. Liquid flow unit: flow (Cc/min), that is, the flow per minute is * * Cc, and cc is the unit of volume1cc =1ml =1cm 3.

Liquid has no fixed shape and is often influenced by containers. But the volume is fixed at constant pressure and temperature. The greater the intermolecular distance of liquid, the more intense the movement of molecules, and the smaller the attraction between molecules. Increasing the temperature or decreasing the pressure can usually vaporize the liquid into a gas.

Precautions:

CC is mainly used to call databases and program pools. These two processes occupy 100% of the CPU, so the server cannot process other access data to achieve the purpose of denial of service, and will not occupy too much traffic. The attacker uses the proxy server to generate a legitimate request for the victim host, disguised as DDOS: cc (challenger ollapsar).

Static pages don't need too many server resources, even reading you directly in memory is fine, but BBS is different. I need to make sure that I have read Washington Post's authority when reading articles in the database system. If so, I will show my access rights to at least two databases here before publishing the content.

If the data capacity of the database is 200mb, the system may search the data space of 200mb again. What is the cost of CPU resources and time? If I want to find a keyword, then time is more important.
