Comparing SQL engines by CPU instructions for DML

This post compares the CPU usage of different SQL engines, such as PostgreSQL, Oracle, SQL Server, MySQL, TiDB, YugabyteDB, and CockroachDB, for simple DML operations. The results show that despite their different implementations, PostgreSQL, Oracle, and SQL Server perform well in terms of CPU usage. TiDB, YugabyteDB, and CockroachDB exhibit higher CPU utilization due to their distributed and scalable architectures. Overall, the performance varies depending on the database engine and workload.
