Benchmarking Postgres 17 vs 18
9 min read
Postgres 18 introduces the io_method configuration option with worker and io_uring alternatives. Benchmarks using sysbench on four EC2 instance configurations compare read-only performance against Postgres 17. The io_uring option enables asynchronous disk reads via the Linux io_uring interface for potential I/O gains.
