i have installed the latest comodo firewall via web installer on a fresh installed windows 10 pro ( i call that system B).
windows 10 pro version 1607 - build 14393.693 - 64 bit
i am on system A with no firewall. i have a 1 gigabit lan connection.
when i copy files (send) from system A to system B i get 114 MB/s.
when i copy files (grab) from system B to system A i get 11-19 MB/s and system B completely freezes. mouse cursor does not move.
when i uninstall comodo firewall i get full speed in both directions and system B does not freeze.
i spend a day installing and deinstalling commodo and tested back and forth.
the problem only occurs when comodo is installed.
i already bought a new switch because i thought the switch is maybe the problem… but no it´s this buggy new comodo version.
i spend 2 days figuring out this error… comodo needs to do some betatesting!!!
when i disable all comodo modules (i have hips, sandbox and viruscope disabled anyway) it doesn´t change a thing.
i have to completely uninstall comodo to make the system behave correct.
i may have to add that it is not the fastest system.
it´s an intel sandy bridge G840 2.8 GHz system with 4 GB ram.
but honestly… it should be fast enough to run a firewall without stalling the whole system.
something from comodo is a REAL resource hog.
i see now… i tried to download via the option for a separate PC (i was not on the PC with the issues that´s why i selected that option).
but when you select that option you only get the full 4.4 GB package.
im downloading the WPT right now.
will do the test and report back.
Gothmoth had been more than helpful in helping us test different possibilities.
Considering problem is very machine specific, it has not been easy to isolate. We will be working in next days with Gothmoth to see if potential fix we think can fix that.
