Note that if we had run it without the above manual tweaks, only 1 out of 4 fixes would have been manually identified because the other 3 depend on user preference and the app’s environment. There’s another tool from Percona which can help us find the remaining problems automatically. On most hosted servers like DigitalOcean droplets you’ll have SSDs, so the I/O system will be high performance.

This should always be done, unless the I/O system is very low performance.

the log file size is well explained here but in a nutshell it’s how much data to store in a log before wiping it.There’s a buffer pool sizing guide available in the MySQL docs. It’s used to keep frequently accessed data in memory, and when you’re running a dedicated or virtual server where the DB will often be the bottleneck, it makes sense to give this part of your app(s) the most RAM. innodb_buffer_pool_size – the buffer pool is a storage area for caching data and indexes in memory.Innodb_flush_log_at_trx_commit = 1 # may change to 2 or 0 As per these tips, add this to the config file under the section: innodb_buffer_pool_size = 1G # (adjust value here, 50%-70% of total RAM) The following manual tweaks should be made out of the box. Note: modify the above path to match the config file’s real location – it’s possible that it’s actually in /etc/mysql//mysqld.cnf Manual Tweaks Otherwise, use a simple text editor like vim by executing sudo vim /etc/mysql/my.cnf. If you’re editing locally on a Vagrant box, you can copy the file out into the main filesystem by copying it into the shared folder with cp /etc/mysql/my.cnf /home/vagrant/Code and editing it with a regular text editor, then copying it back into place when done. Even if you haven’t been exposed to it yet, now is as good a time as any. You’ll need to be comfortable with using the command line. It’s possible that your installation will actually load a secondary configuration file into that configuration file, so look into that – if the my.cnf file doesn’t have much content, the file /etc/mysql//mysqld.cnf might. We’ll assume you’re using a Linux-based host or a good Vagrant box like our Homestead Improved so your configuration file will be in /etc/mysql/my.cnf.

5.7 (the current version) has much better defaults than its predecessors, but it’s still easy to make improvements on top of those.
#MYSQL OPTIMIZER SETTINGS UPGRADE#
The first – and most skipped! – performance upgrade every user of MySQL should do is tweak the configuration.
