The Middleware of Long Transaction, High Concurrency and Frequently Active Servers Performance Optimization

摘要

Long transactions, high concurrency, and frequent activity situations occur in many areas. The intermediate process of long transactions in the process of execution is more, in the process, therefore, can not avoid frequent access to the data, the system overhead of the data access process is relatively large, which reduces the efficiency of the system and increase the pressure of the server. The impact of the high concurrent to server is mainly in the calculation. When problems such as long transactions and high concurrency occur simultaneously on the server, the server pressure will suddenly rise and this will seriously affect the server's processing efficiency. After analysis, the main reasons for the increased server pressure are two: data access and processor computing. The article gives some suggestions from these two respects to optimizes.
