Slow Copying Speed

Hello everyone,

Okay, so here's the situation. We just upgraded our Trend Micro OfficeScan from v8.0 to v10.5. Before this upgrade, I was able to transfer data over our network, to my computer onto an external eSATA drive each day at about 10-40MB/S (higher 30's most of the time). After the upgrade, I now can only get about 1MB/S. Now, of course I thought this would come with the Real-Time Scanning feature of OfficeScan, so I disabled it. Nothing. And I still cannot figure out why this thing has taken such a decrease in performance with the only change being the OfficeScan upgrade.

As a note, I will be testing on another computer tomorrow to make sure that it's not just the that, or if it is, as one of the more simple tests after I configure the firewall. Ping results turned out fine, but I didn't expect it to have any issues there.

Thanks for the suggestions, and if I missed a tag or put it in the wrong place, I'll change it if I can.

When you upgraded to v10.5, did you shift to Smart Scan mode or are you still using the Conventional Scan? If it's the former, it might have some performance issue during the initial phase of the deployment since the clients will need to establish their cache, but this lag will soon go away once the cache is established.
If you are on Conventional Scan, then try setting your realtime scan setting to use IntelliScan instead of Scan All files and see if it will make a difference.

Finally, I would NOT have chosen OfficeScan because it has no benchmark available from http://www.av-comparatives.org/en/comparativesreviews/performance-tests or http://www.clubic.com/article-77079-2-guide-comparatif-meilleur-antivirus.html or anywhere I googled for it...

Younghy,

My OS is Windows 7 64bit while the server is Server 2008 R2 or even Server Standard 2003.

BigSchmuh,

I will try making those settings when I get the chance and let you know. Right now, the settings are set to Smart Scan.

Reason we stayed with OfficeScan is because I just started here about a month ago, and while I wanted to switch it up and go to something else, like Kaspersky or Avast, my boss wanted me to stick with learning the systems around here instead of trying to migrate to another virus scan. I will probably suggest this once the license expires.

So when you transfer the data which of the process or application is taking most of the CPU?

Use taskmanager or for detailed processes use Process Hacker or Process Explorer. I prefer Process Hacker as it does not require .Net Framework to work, plus it has additional plugins which offer more functions than Process Explorer.

Download:

or

Process Explorer

My opinion is that, after studying the brief workarounds I suggested above, you have a clear case to run for a new anti-virus (downgrading to 9 or back to 8 in the in-between)...even the free AV ones looks operating better.

Just found out the complete solution.

I'm not sure why this setting would have changed at All, but I went to the Local Area Connection adapter, properties, configure and found out that under the advanced tab, 'Link Speed & Duplex' was set to 10MBPS Half-Duplex. I changed it back to Auto-negotiate and Bam, right back to the speed it was supposed to be at.

Again, not sure why that happened, but it's working now.

Just as a note, I did try turning Real-Time Scanning back on and it did kill performance again, but not as bad as it was.

Thanks for the suggestions guys.
