In the WAMP combination, sometimes even if there is no visitor, mysqld.exe will occupy about 400M of memory, how should such a problem be solved?
Mysqld.exe takes up too much memory, which mysql request may be stuck and the response time is too long. Try to open the slow log, then look at the slow log to see which statements have too long response time and try to optimize! !
Just speculation! ! I don’t know if it works, it doesn’t work!
