5.8.2 Resource Bottlenecks Caused by Virus Scanners
If there are several VMs running on a particular ESX server and there are any virus scanners installed on
these VMs, these virus scanners should be set up so that they wouldn‟t start their virus check cycle at the
same time. If so, they may cause substantial bottleneck on system resources, especially CPU and disk
bandwidth, and as a consequence, fax transmission error rate may increase dramatically during such a
period of time.
