Slow gigabit throughput on CIS 3.9.95478.509

Im running the Free Firewall with no Defense+ and no AV. The gigabit throughput with the firewall about 200Mbps download and 300Mbps upload. With the “COMODO Internet Security Firewall Driver” unbound from my TCP/IP interface i get 500Mbps+ down and up.

Does Comodo’s firewall driver slow packets down that much when its enabled?

Tested on Windows 2003 server x64

Not sure how you managed to install on Windows 2003 server x64
