MySql Query cache on Windows

Slow server? Check if your query cache is set by querying:

mysql> show variables like 'have_query_cache';
 | Variable_name | Value |
 | have_query_cache | NO  |

How to enable this?
Find your my.ini … in my case in: C:\ProgramData\MySQL\MySQL Server 8.0
Add under [mysqld]

query_cache_size = 268435456

More info here:
And as you will notice this is 5.6 documentation. In my case this does not work, because I am using MySQL8.0 …. The query cache is deprecated as of MySQL 5.7.20, and is removed in MySQL 8.0.
