Out of the box, the default PostgreSQL configuration is not tuned for any particular workload. It is primarily the responsibility of the database administrator or developer to tune PostgreSQL according to their system’s workload. What is PostgreSQL performance tuning? Why is PostgreSQL performance tuning important?

Compare ease of use across compatibility, extensions, tuning, operating systems, languages and support providers. Scalability. PostgreSQL offers free scalability, and can scale up to millions of transactions per seconds. Oracle Enterprise is recommended for high workloads which are highly scalable, but costly. PostgreSQL.

HammerDB doesn’t publish competitive database benchmarks, instead we always encourage people to be better informed by running their own. So over at Phoronix some database benchmarks were published showing PostgreSQL 12 Performance With AMD EPYC 7742 vs. Intel Xeon Platinum 8280 Benchmarks . bin/createdb pgbench./bin/pgbench

Some opinions claim that “Benchmarks are meaningless”, “benchmarks are irrelevant” or “benchmarks are nothing like your real applications” However for others “Benchmarks matter,” as they “account for the processing architecture and speed, memory, storage subsystems and the database engine.”

MySQL is not written in NodeJS, but we specify –lang node to launch the perf profiler, which is compatible with C/C++. Manual flame graphs collection Although the tool is excellent and automatically provides flame graphs, we don’t have much control over tuning the selected profiler.
