Symantec Personal Firewall Can Slow UDP Traffic Print


In some instances Symantec Personal firewall limits the speed of UDP traffic. Speeds as low as 68Mbs on a Gigabit network have been observed. Other firewall software may exhibit similar behavior.


The configuration options for the firewall software should be reviewed to see if the UDP examination behavior can be switched off. TCP traffic may prove to be faster for workstations with personal firewall software.
