Users home drive extremely slow to open all files
We just created a new file server, 2008 r2 4 gig ram 2 xeon processors and are having issues with their home drives and other shares. we have 2 different shares, the Student Data share and the Home share. When you try to open any files in the users home drives though it takes about 10 to 15 seconds. In office applications it even says downloading <filename> before it says opening <filename>. This is happening with all users. The shares are both on the same drive and permissions have been verified and even recreated. All clients are Windows 7
Any help is greatly appreciated.
**Edited question. originally thought the student data folder wasn't having the issue, but have discovered that it is indeed having the same issue.

I gues soem more info would help. How many users. Whats the disk config on the server? SATA or SAS? Raid? Network ports?
As its server 2008 r2 the built in PERFMON (just run it from the command line) has pretty good diagnostics for performane problems.) Check the physical disk avge sec/io is below 200ms.
You might also want to download spotlight
http://www.quest.com/spotlight-on-windows/
its pretty good at highlighting server bottle necks, it will highlite any bottle necks
Lastly look at your anti virus product. Is the desktop and server products fighting. Is the server and the client both scanning the same file...

I will run perfmon and download spotlight and see if that points to anything
The server is a virtual server. We have another identical server that is having no issues at all. We the Anitvirus is Eset and we were not having these issues with the previous fileserver which was on the same physical host server. Plus the other fileserver for the staff has the same AV setup and not having any issue.
The disc config of the host is SCSI in raid 5
Network speed of the server is an Intel PRO/1000 set to auto negotiation. This is also identical to the virtual server on the same host that is not having any issues.

download "Netio" from http://www.ars.de/ars/ars.nsf/docs/netio
this is a little nifty helper.
Copy it to two machines (two servers).
On the first start it via commandline : netio -t -s
On the other server (the slow one) run it via commandline: netio -t servernameFromOtherServer
The output should look like this on a gbit-link:

I will take a look at that Netio.

That's the results from the utility. We don't have gig switches, but we didn't before setting up the new File Server and it was working fine before so I don't think it's a bandwidth issue (it even takes a long time to open like a 10k file)

the netio-results show that your network performance is far beyond GBit....looks like 10Gbit-Link - never seen such high results before :-)
pls do the test again between the "slow" server and a client which is encountering the slow connection.

Will test that on Monday. Didn't even notice my results were MBytes and not KBytes hehe. Just saw the number and thought it was slow :)

Here's the results from a client that is having slow connection

It happens on files that are even under 20KB I will test opening files multiple times.

We disabled the AV on the client and it made no difference. We disabled it on the server and it resolved the issue. We will uninstall and reinstall the AV on the server and hopefully it won't become a problem again. We have the same AV on other file servers and don't have any problems so it should be fine with that program but we shall see. I will let you know what happens after the reinstall.
Thanks for all the help.
Thanks for all the help.
glad to hear that you FOUND the problem :-)
We're NOT using a av-solution on the file-servers.
That long that no one is using the internet on the fileservers or opening any files i don't see any security reason PRO av on a server....but that discussion maybe will never come to an end .-)

Thank you for the help. Never thought it would be the AV since it's on all the other file servers with no issues.
May be it is simply a network-card (switch) issue ?
1000Mbit Full Duplex ?
