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:

Bash/zsh completion
use Tab to populate command line, narrows down options as you go, fills in container names, ID's, images, volumes. Huge time saver.

	Django ORM Optimization Tips

	Caveats:
	* Only use optimizations that obfuscate the code if you need to.
	* Not all of these tips are hard and fast rules.
	* Use your judgement to determine what improvements are appropriate for your code.
