3 Steps to Unlock Postgres Performance
Learning how large the speed gap is between an in-memory database and a relational database is eye-opening. A simple way to show the enormous raw data processing differential between Tarantool and PostgreSQL is to examine how many transactions the systems can perform per second, per CPU core.
Tarantool can easily be added to an existing Postgres stack using its Postgres connector, and the system can process up to one million transactions per second on a single core — whereas the successful execution of one million transactions per second in Postgres and other relational databases requires an extremely powerful server running from 2 to even 723 cores.
