default value "Standard" represents the old hash policy using the previous version.; Set to "consistent" allows you to add/Remove servers in a connection pool without having to recalculate the mapping relationship between key and server.; memcache.hash_strategy = "standard"; Controls the hash function that maps the key to the server. The default value, Crc32″, uses the CRC32 algorithm, whereas "FNV" means the FNV-1A algorithm is used.; The fnv-1a is slightly lower than the CRC32 speed, but the

The Code is as follows: CalculateSalary Method 1 [WebMethod]2 public string CalculateSalary(Employee employee)3 {4　　 return "I'm " + employee.RealStatus + ", my salary is " + employee.CalculateSalary() + ".";5 } In this way, we only need to input instances of different Employee subclasses to obtain different information. Now let's start allocating salaries (the following figures are purely fictitious. If there are similarities, it's a coincidence )! First, interns. Poor

(such as mysql), the value is smaller than 200. You cannot allocate all the memory of the operating system to apache? 3. each browser is a user, and each user is a process. Do you understand the meaning? The concurrency of my server is only 200. That is to say, my server can only support access by 200 users at the same time, and more users can only wait for access. Or my server only supports access from 200 browsers. I will explain the server concurrency in detail in the following article. Is
