How to optimize InnoDB memory parameters for performance? - mysql

Question

I am using Mysql server 5.6. I don't have much idea about setting in my.ini file under MySql folder.
In my my.ini file the memory pool size is set to 679M. We are using InnoDB engine for mysql. Can I change the memory pool size? If yes, how much memory I have to give for better performance? Here below I specify my my.ini file settings.
What are the required settings for the Innodb engine?
Please mention settings which are unnecessary in my.ini file if engine used for mysql is innodb.
My my.ini file:
default-storage-engine=INNODB

See memory for discussion of what to set it to. (It depends on how much RAM you have available.)
Those settings need to be in the [mysqld] secdion of the config file. The value look like they were generated by some install script; they are probably reasonable. Most people do not need to touch the config, especially if the install script does things such as adjust for RAM size.
To have my.ini (or my.cnf) values take effect, stop and restart the server. The details of that are OS-dependent.
