How Much memory do you use to run MySQL

 | November 2, 2012 |  Posted In: Insight for DBAs, MySQL


We have seen number of issues with MySQL Server related to amount of memory you have in the system – these range from problems with large size Query Cache to bad drop table performance with large Innodb Buffer Pool size. As such I wonder how much memory do we really use to run MySQL Server these days ?

Feel free to select multiple sizes if you have multiple kinds of instances in production and for boundary numbers please select the highest range which applies, ie for 16GB system select 16-64GB range. Thank you for your feedback ! I will keep the pool open until the end of the year when it will be frozen so we do not get results from multiple years mixed.
