Intel Demonstrates Up to 48% Improvement for AVX-512 Optimized PostgreSQL
Intel's AVX-512 optimizations for PostgreSQL 17 enhance performance by up to 48%, particularly with the pg_popcount() function and SIMD-optimized JSON escaping, as detailed in a technical paper.
Read original article
Intel has reported significant performance improvements for PostgreSQL 17, particularly with the introduction of AVX-512 optimizations. The new implementation of the pg_popcount() function, which processes data in larger 512-bit chunks on compatible hardware, has shown performance gains of up to 48% for the bit_count() function. This enhancement is part of a broader effort to leverage AVX-512 instructions for better efficiency in database operations. Intel's findings indicate that these optimizations can be particularly beneficial for larger data buffers. Additionally, PostgreSQL has also seen improvements in query performance through SIMD-optimized JSON escaping. The upcoming PostgreSQL 17 release, which is currently in the release candidate phase, is expected to include these optimizations along with other new features. Intel has published a technical paper detailing these advancements, and further proposals for AVX-512 usage within PostgreSQL are also in the works.
