Im running the Free Firewall with Defense+ and no AV. The gigabit throughput with the firewall on is about 300Mbps download and 600Mbps upload. With the “COMODO Internet Security Firewall Driver” unbound from my TCP/IP interface i get 700Mbps+ down and up. Testing was done on a Cisco 3560G switch and the speedtest server is on the local lan segment.
Does Comodo’s firewall driver slow packets down that much when its enabled? ???
Tested on both Windows XP SP3 and Vista Ultimate.
Nothing else is checked other then what was listed above. This is a completely default install with no custom tweaks. Also, when I tested the 3.9 I uninstalled 3.8 first and then installed 3.9 from the setup files.
Currently running CIS_Setup_3.9.76924.507_XP_Vista_x32. I assume this is 507? I just downloaded this from the website today.
I have a Visualware speedtest server on my local LAN setup to test. Also, I’ve tested with iperf and the results was always slower when the Comodo Firewall driver was bonded to the TCP/IP nic interface.
I often use TTCP but have not tested 3.9 with it, are the error counters on your Cisco box clean ? and do they resemble the same 5 min avg in/out load for the traffic ? (or maybe set “load-interval 30” to have faster updates).
Are any of those tools free to use ?
And one other thing, have you tested it with the driver attached to the NIC and the FW set to disable ?
Is it still slowing the system down ?
As for the Cisco switch its showing no errors, CRC, etc…
Visualware has a free 30day trial, where IPerf is a free utility (one side is server and the other side is client).
Just googled iperf.exe and found it on this site http://www.noc.ucf.edu/Tools/Iperf/iperf.exe
Its a slightly older version but it still works fine.
From a windows dos terminal type:
iperf -su (Workstation #1)
iperf -c 192.168.1.1 -b 1000M -t 30 (Workstation #2- *Note- 192.168.1.1 is the ip of Workstation#1)
When I have FW/Defense disabled it still runs slow, but the second i unbind it from the TCP/IP properties its blazing fast. That’s why i have a hunch its how the fw driver is shimmed on the nic interface.
Each test was done twice.
Only Workstation #1 has Comodo installed.
Iperf setup to run 2 processes with 128KByte TCP window size for 30 seconds.
Both computers setup on same Cisco 3560G (GigaBit Switch running at Giga).
