I am new to postgres using OS: linux 7.2 and postgres : postgresql-9.5.4-2.
what are the factor's affecting postgres performance? and to overcome them.
- CPU speed,
- cpu core count (if you have significant concurrency),
- memory size,
- disk IO speed (especially small block random write ops/second for insert/update intensive OLTP),
- database schema design,
- query design,
- administrator and developer knowledge.
in no particular order, any number of those can be critical depending on the nature of your applications.
