I personally feel that this platform has poor autonomy, whether it is for customers or carriers. For customers, this platform is a virtual operating system and cannot be set on their own in many aspects. It is typical of Windows virtual memory management, which is not good. For sellers, the operation of this platform is inseparable from the support of swsoft. Of course, small-scale operators do not have enough technical strength to maintain the platform, but they must still be unable to do witho

Sysbench Introduction
Sysbench is a modular, cross-platform, multithreaded benchmarking tool that is used to assess the load of databases under various system parameters. It mainly includes the following methods of testing: CPU Performance Disk IO Performance Scheduler performance memory allocation and transmission speed POSIX thread performance database performance (OLTP benchmark)
