. Therefore, setting Table_cache to thousands of does make MySQL slow. (The benchmark also proves this point.)You can passSHOW GLOBAL STATUS;View the performance information of the system and calculate the number of open per second (Opens/second): Opened_files/uptime, if the value is larger, for example, greater than 5, then the table_cache should be increased; If it is small, such as 1, it may improve performance by reducing the Table_cache value.Query CacheA short answer: setQuery_cache_type =

Some people ask whether the QueryCache (QC) Lock in MySQL is a global lock or a table lock. Here is a brief description. 1. Basic Concept of QC this is a memory structure implemented on the MySQL layer (non-engine layer). The basic rule is to cache query results that meet certain conditions in the memory, if the same query is executed for the second time and the cache is not invalid, you can directly return

the object to be tested.2. Use the description objectTo use the description object, use code similar to the following:Set mydescription = description.

Before upgrading td to QC, I used various upgrade methods. However, it was found that importing defects to the QC database using Excel is the easiest and convenient method. The implementation steps are as follows:1. First, log on to TD, display all information about the defect on the interface, and then use the defect tool to save all the defects on the page to the Excel table;2. Create a new project in
