Today I'm changing the memory speed on my main test system, going from 2133MHz to 3200MHz, and measuring how that impacts PostgreSQL SELECT results. I'm seeing a 3% gain on this server, but as always with databases that's only on a narrow set of in-memory use cases.
This week Apple started delivering Macs using their own Apple Silicon chips, starting with a Mac SOC named the M1. M1 uses the ARM instruction set and claims some amazing acceleration for media workloads. I wanted to know how it would do running PostgreSQL, an app that's been running on various ARM systems for years. The results are great!
Apple's Intel-based laptops are very popular among developers, and that's as true of people who work on PostgreSQL as other groups. Tomorrow, the first shipping Apple laptops running on ARM CPUs instead of Intel are expected.
PostgreSQL 13 was released last week. I'm excited about this one, as the more mature partitioning plus logical replication features allow some long-requested deployment architectures
