Stephan, Your advice (check the process list) gave me an important clue for my solution. I changed my database connection to the slave instead of master, so that I can use more threads. Thank you very much!
*** François, My setting is the default value: max_connections = 151 max_user_connections = 0 I will think of changing the max_connections when I increase the number of cores. Thanks! *** Fuad, So far, I can handle DIH with my setting. Thanks for letting me know!
