20% performance loss using Openvz isn't normal. Think of openvz as resource containers with tools to view container stats on the HN, and when a PID is in the context, it has many restrictions to "stay" in its context.
Other, true and heavier virtualization architectures such as vmware, xen, etc introduce an interface for the virtualized kernel to talk to the underlying HN. This is where a performance loss is induced.
20% is extremely high, and very unexpected.
