Mysqlslap is an official MySQL-provided stress testing tool starting with version 5.1.4. Perform stress testing by simulating multiple concurrent client access to MySQL while providing detailed data performance reports for "High load attack MySQL".

First, the method Copy Code code as follows: /** * Execute a shell command and return the string value * * @param cmd * An array of command names & parameters (for example: {"/system/bin/cat", "/proc/version"}) * @param workdirectory
