The blog post, authored by Charlie Custer, provides insights from the 2022 Cloud Report on the performance of various Google Cloud Platform (GCP) instances for Online Transaction Processing (OLTP) workloads. It details the results of tests conducted on 18 different GCP instance types across more than 3,000 runs, focusing on overall median transactions per minute (TPM), median TPM per virtual CPU (vCPU), and price-for-performance using a Cockroach Labs TPC-C Derivative Nowait metric. The t2d instances, featuring AMD Milan processors, consistently emerged as top performers in various categories, including overall performance, per-vCPU performance, and cost efficiency, often outperforming larger nodes and high-performance storage configurations. The report also offers comparisons with similar instances on AWS and Azure, providing comprehensive benchmarks for CPU, storage, and networking performance, and is available for free to assist GCP customers in selecting the optimal instance for their OLTP workloads.
