MySQL on Mac for TechEmpower benchmarks

I always forget how to do this, so this is a note to myself.

I’ve already installed MySQL on my Mac with Homebrew.
Start MySQL.
```
mysql.server start
```
Create the user accounts, schema and data.
```
sudo mysql  < config/create.sql
```
Since I’ve never worked out how to increase MySQL’s max number of connections, I manually decrease the size of the connection pool in every Play app’s application.conf
```
db.default.maxConnectionsPerPartition=5
db.default.minConnectionsPerPartition=5
```
