Summary

There are instances when the Smart Scan Servers (integrated or stand-alone) encounter high CPU usage during a scheduled scan when there is a large number of Smart Scan clients. However, after the scheduled scan, the performance drops to an acceptable level.

Smart Scan server requirements:

Officescan 10 SP1 (EOS) Integrated Smart Scan Server
ProcessorAt least 1.86GHz Intel Core2Duo™ processor if installing the integrated Smart Scan Server
RAM1GB minimum if installing the integrated Smart Scan Server
Smart Scan Server Version 1.1 Service Pack 1 Build 1166
Processor2.0 GHz Intel(TM) Core2Duo(TM) 64-bit processor supporting Intel(TM) Virtualization Technology(TM) or equivalent
RAM1GB RAM

To alleviate this scenario, consider increasing the number of CPUs associated with the Smart Scan servers. If you are using a virtual machine solution (Microsoft Hyper-V or VMware ESX/ESXi/Server), please consult your documentation on how to accomplish this.

It will also be beneficial to spread the processing load across the virtualization hosts or images. For example:

  1. Separate the OfficeScan server from the Stand-alone Smart Scan Server between  virtualization hosts if they are hosted on one host only.
  2. Increase the number of virtualized images of the Smart Scan Servers on the environment, but use separate virtualization hosts to spread processing load.
