Slow writing to FreeNAS network drive with Antivirus Plus 2010

Jump to solution

Hi there,

Here are some background information,

Main PC

OS: Vista Business 32bit

CPU: i7-860

RAM: 4GB DDR3

NIC: Realtek 8111DL 1000Mbit

FreeNAS

OS: FreeNAS 0.7 Khasadar (revision 4919)

CPU: P4 2.4Ghz

RAM: 2GB

NIC: DGE-530T

I'm facing slow network write issue, less than 200KB/s... After i uninstall antivirus plus 2010, the speed jump back to 50MB/s

Do it need to tweak any firewall setting to fix the issue? Any idea how to fix the problem....

Regards,

SR

Hi,

Could you please confirm whether you use the enterprise version of Mcafee or the home version ? ;

I am having the exact same issue: very slow writing performance to all network drives.

Diabling firewall and on-demand scan has no effect -- writing is stil slow.

Uninstalling McAfee solves the problem.

Problem re-appears after re-installing McAfee.

McAfee version:

McAfee AntiVirus Plus

McAfee Security Center version 10.0 build 10.0.570

McAfee VirusScan version 14.0, build 14.0.306

McAfee Personal Firewall version 11.0 build 11.0.378

McAfee Virtual Technician gives a clean bill of health.

...Clarification: slow writing issue appears to affects all network drives -- regardless of where they are hosted: Windows XP, 2000, or NAS.

Similar problems here with  Internet Security 2010 (9 seats)

PCs: ASUS Mobo with Nvidia chipset using on-board NIC

Gigabit wired LAN

Network Storage: LG N2B1 (Raid 1)

Mixture of Operating Systems:

Windows XP: Good upload & download speeds  (eg 218 MB in seconds)

Windows Vista: good download speed, UNUSABLE upload  (eg 218 MB in 45+ minutes!)

Windows 7: good download speed, UNUSABLE upload  (eg 218 MB in 45+ minutes!)

IS2010 not installed: good upload & download speeds

I have read elsewhere that this problem has been known for several weeks (one post I saw was dated late March). A recent post suggests that a bug fix is due tomorrow (Monday).

today's update as was mentioned by tech support, for MF TP Security Center 10/VS 14 did not alleviate the problem sadly.

i neglected to mentioned that im not using a NAS, but merely a 'normal' windows share on another computer. same problem otherwise

interrestingly, if i reinstall but only chose AV and not MF Firewall the problem remains. so no firewall in other words, including no Windows firewall.

makes me think its something in either the scanner or that new Traffic Monitor thing in TP

Im not sure what FreeNAS is but I'm having the same problem with a IOMEGA Network Drive. I have a laptop running Windows 7 and a desktop with Vista Ultimate, both running Mcafee Total Protection. When uploading to my drive I can only get 75KBps which is unacceptable. So after looking all over and finding lots of people with the same problem it's evident that Mcafee Firewall is blocking the data transfer somehow. The only thing that has worked for me it's disabling the firewall then unplugging and plugging back in the netwok cable. Guess what I got? 8MBps tranfers! So if anybody at Mcafee even bothers reading theses posts please make sure to implement a fix on your next release because it makes no sense paying for software that you have to disable in order to fully use your hardware.
