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  http://pgmag.org/
