Choose the Right Azure Infrastructure to Improve Postgres Performance by Over 60%
summary
Azure v7 AMD VMs like E16asv7 deliver a measured 63% raw throughput uplift versus a five‑year‑old E16asv5 and a 54% throughput‑per‑dollar advantage, cutting compute cost for the same work by ~35%. Dropping to an E8asv7 halves cores with ~9% throughput loss but ~170% throughput‑per‑dollar gain and ~63% OpEx savings. Confidential VM modes add ~3–6% overhead. Phoronix benchmarks show AVX‑512 yields ~45% average gains, and DiskANN claims up to 10x speed, 4x cost reduction, and 96x lower memory versus HNSW.
