# Optimizing postgresql table for more than 100K inserts per second

* Create `UNLOGGED` table. This reduces the amount of data written to persistent storage by up to 2x.
* Set `WITH (autovacuum_enabled=false)` on the table. This saves CPU time and IO bandwidth
  on useless vacuuming of the table (since we never `DELETE` or `UPDATE` the table).
* Insert rows with `COPY FROM STDIN`. This is the fastest possible approach to insert rows into table.
* Minimize the number of indexes in the table, since they slow down inserts. Usually an index
  on `time timestamp with time zone` is enough.
* Add `synchronous_commit = off` to `postgresql.conf`.
* Use table inheritance for fast removal of old data:
