Firewalls and anti ‐ virus software
Depending on the system configuration, the following software may have a
significant impact on throughput and CPU utilization, in particular when receiving
multicast UDP traffic:
• the built ‐ in Windows Firewall and Base Filtering Engine
• other third ‐ party firewall or network security products
• anti ‐ virus checkers.
This is the case even if the software has no rules configured but is still active.
Where high throughput is required on a particular port, the performance will be
improved by disabling the software on that port:
NOTE: The Windows (or any third party) Firewall should be disabled with caution.
The network administrator should be consulted before making any changes.
• Disable the Windows Firewall.
a) Set the Startup Type of the Windows Firewall service to Disabled .
b) Stop the service.
• On Windows Server 2008 R2 disable the Windows Filtering Platform (WFP).
a) Set the Startup Type of the Base Filtering Engine (BFE) service to Disabled .
b) Stop the service.

• Disable (and if possible uninstall) any third ‐ party firewall or network security
products, and any anti ‐ virus checkers.
Remember that even the simplest anti ‐ virus products can inspect network
traffic to look for viruses in e ‐ mails.
