The Redis Cache server is a keyvalue database that reads 110000 s and writes 81000 s. it is fast because it is a memory operation, common usage is to store user tokens, text message verification codes, and other official websites to show that Redis itself does not have a Windows version, Microsoft officially developed a Windows-based Redis server: MSOpenTechredis

number of pages VM-max-threads num # The number of worker threads that execute value exchange can be kept in multiple pages, however, only one value can be saved on a page. No value can be saved until the memory used by redis does not exceed VM-max-memory. Exchange any value. When the maximum memory limit is exceeded, redis preferentially selects expired or large objects for switching: swappablility = age * log (size_in_memory) VM-max-threads = 0, the blocking virtual memory is enabled and I/O
