Thank you for reporting, could you please specify the application which made slow transfer when Comodo firewall driver is enabled ? or share us exactly what you did and what happened.
Also, provide us the below details:

Hi there,
This is version Comodo Internet Security 2020 v12.2.2.8012, i tried the comodo firewall in a clean install and i have same issues.
I have another PC with This same version with Windows 10 pro x64 21h2
I usually copy files between my 2 pcs. Both are gigabit connected, with network shares. ( smb). When i copy/move files between 2 pcs i use na tive Windows Explorer. I tried teracoypy and have same problem. Usually get 80 MB/s. When i disable comodo firewall driver i get around 114 MB/s. I have not another security software instaled.Just out of box Windows defender. If i not install cis i get around 114 MB/s too.
Thanks
