parameter that directly measures system performance.. 4.Concurrent users Concurrency is generally divided2. One is strict concurrency, that is, all users perform the same thing or operation at the same time. This operation generally refers to the same type of business. For example, in the Credit Card Approval business, a certain number of support personnel submit completed approval services at the same time. There is also a special case that all

As we all know, Mysql paging requires the use of Limit for paging. When the data size is small, the Limit performance can be imagined. For example: {code...} the preceding SQL statement has no performance problems. However, if the offset is too low, a performance bottleneck may occur. For example, {code... as we all know, Mysql uses Limit for paging. When the dat

Performance of network protocolsNow it's our turn to actually control things.The performance of network processing is not proportional to the addition of delay time.This is because the intrinsic operation of most network protocols is bidirectional information exchange.The remainder of this chapter focuses on understanding why these exchanges of information are generated and how to reduce or even eliminate t
