Can the performance of Postgres be boosted, especially on busy systems, using the none default DEADLINE Scheduler?
Some system reports moderate improvements in throughput, and sometimes larger ones in worst-case latency, when switching from the default to the deadline scheduler. Others report best performance with the noop schedule. Changes here are not effective in a lot of cases though.
I wrote an article for the first issue of PostgreSQL Magazine that mentions this, as the last of the most useful things you can tweak on Linux; that's available at
