|Managing Pivotal GemFire / Performance Tuning and Configuration|
This topic provides guidelines for tuning vSphere virtualized environments that host Pivotal GemFire deployments.
Without tuning, GemFire can suffer a performance drop in virtual environments, including the VMware vSphere virtual platform. You can expect to see significant performance degradation when running GemFire on vSphere versus running GemFire on dedicated hardware.
Pivotal GemFire has been certified and tested on vSphere 5.0.
