Degraded Performance when Gateway Anti Virus is Installed (Large Speed Decrease)

Resolved
0 votes
Hey All -

I'm running ClearOS 7.1 (Final) and have a 1G/1G fiber connection, as such I am running ClearOS 7.1 on pretty robust hardware for home use:

Intel Core i7
32 Gigs Ram
500 GB Hard Drive
Intel Dual Gigabit NIC

I am able to reliably get around 950 down and 910 Up (within specs) with a vanilla Clear OS 7.1 install.

Things take a turn once "Gateway Antivirus" 2.1.15-1 is installed. My speeds then fall on average to around 350 GB with just this one marketplace app installed.

Once I uninstall this application speeds return as normal. Is this particular application not multithreaded or able to support this speed? If not, will it be upgraded to do so?

Thanks

    Ouch! That means, even at full SATA3 speed (600MB/s) with a blistering SDD, you can still only really support a 300Mb/s line speed - not that it bothers me with my connection.

    Hi JPrez,

    Gateway AV is done via the web proxy, so disk I/O becomes a bottleneck on fast networks like yours. Take a look at this technical document for more information and tips & tricks:

    Wow - I could only dream of such speeds :-)

    I don't know if the Gateway AV app has been benchmarked for throughput at gigabit speeds? I suspect the bottleneck is the single core processing of the traffic bandwidth but I'm only guessing. Have you tried looking the output of 'top' command whilst running? (press 1 when running to show each CPU usage)
