I have a weird issue, when I checked my app/log/dev.log I can see almost all of my queries in my dev.log being logged in real time:
You should use prod env on your production server. In the prod env doctrine's logging is disabled by default.
But if you want to disable logging at all (in all environments) you need to set up a config.yml like that:
doctrine:
dbal:
connections:
conn1:
driver: ...
...
logging: false
profiling: false
