VMware vFabric Postgres 9.2 Performance and Best Practices
Sep 30, 2013
This white paper presents the performance of vPostgres 9.2. We show vPostgres 9.2 in a 32-vCPU virtual machine on vSphere and a 32-core physical machine achieves the same vertical scalability as in an equally-configured native setup. Using out-of-the-box settings for both vPostgres and vSphere, we show a VM-based database consolidation approach performs on par with alternatives when memory is undercommitted and increasingly better when memory overcommitment escalates. We also show the vPostgres database memory balloon technique can help better preserve performance under memory overcommitment. We last summarize key best practices for running vPostgres on vSphere.
