Tuning Postgres
|
||||
===============
|
||||
|
||||
The default settings should be fine for most deployments. For larger scale
|
||||
deployments tuning some of the settings is recommended, details of which can be
|
||||
found at https://wiki.postgresql.org/wiki/Tuning_Your_PostgreSQL_Server.
|
||||
|
||||
In particular, we've found tuning the following values helpful for performance:
|
||||
|
||||
- ``shared_buffers``
|
||||
- ``effective_cache_size``
|
||||
- ``work_mem``
|
||||
- ``maintenance_work_mem``
|
||||
- ``autovacuum_work_mem``
|
||||
|
||||
Note that the appropriate values for those fields depend on the amount of free
|
||||
memory the database host has available.
|
||||
|
||||
