I have two brand new Win7 Home Premium 64-bit systems I am setting up. One an HP desktop x4 3.2 GHz, 8 GB RAM. The other a Toshiba laptop x2 2.8 GHz, 4 GB RAM. I am connected to my router via network cable for the desktop and via wireless for the laptop (although I've connected the laptop to a LAN cable and had the same results so it is not a wireless issue). Copying files from one system to the other (via Homegroup) is too slow (1.5-2.5 MB/s). Also opening files on one system where the file resides on the other system has unique behavior that may help diagnose: If I open a read only file like an image (jpg, png, etc.) or a pdf it opens very quickly, even for fairly large files (tested up to 10-20 MB). If I open a simple 5 kB text file in notepad or MS Word, it can take 5, 10 even 15 seconds to open. Try the same for a larger 1-2 MB file and better go get a soda as it can take over a minute to open. Same can be said when I try to save it after making a change. Again better have something else to do! This is so disappointing that on new systems with new OS, new drivers, with all Windows updates I have this kind of performance. Any help would be greatly appreciated. I've read many forum posts and tried a fair amount of fixes but to no avail. I've reset everything back to the original settings after it failed to improve performance to avoid "corrupting" my OS install.

Hi, Do you have any antivirus installed? Most products have different "on access scanning" options, you might find you're configured to scan on write but not read. I'd look the disable AV+Firewall just to double check timing ...don't forget to trun them back on after the test ;o) J

Thanks John!!! I turned off Windows Firewall and Webroot antivirus and the slow access issue disappeared. Snappy as desired! I then turned Windows Firewall back on and it was still snappy as desired! By process of elimination I found that I could have Webroot on and as long as the "File System shield" was not active my network access was "instantaneous" as desired! Obviously I don't want to have that component turned off so I've submitted a tech support request to Webroot for help. Possibly un-installing and reinstalling will fix the problem? I'll see what they recommend. Thanks again for helping determine what has caused 4 weeks of frustrations! If you have any suggestions on the Webroot issue that would be great too! Kevin

Glad to be of help. I've not used webroot but if it's like other AV/Firewall's I'd look to trust the remote computer "\\computername\share" as I assume you've got av/firewall on that box to. J

John, I haven't responded lately as I've been working with Webroot tech support. They helped me do some troubleshooting, including an un-install and a re-install but this did not solve the problem. The latest communication from them follows: "After I had this escalated to the tier 2 team it was determined that this was a known issue and will be addressed with our future build. I apologize for the delay in response and for your inconvenience and you will be notified when the new build is released. We greatly appreciate your support of Webroot products and services. Sincerely, Paul D. The Webroot Technical Support Team" So now I'm in a holding pattern if I want to continue to use webroot. I'll give them a bit of time before I'll have to go to another anti-virus solution. Kevin
