Choppy file shares from Windows 7?

[spacelord]

I have run XP for many years, and set up a share of videos which I have been able to watch from an XBOX running XBMC.

Now that I have upgraded both computers to Windows 7, the navigation of folders and starting a show is really slow. This behavior is the same if I try and connect to either of my Windows 7 machines.. both totally different Motherboards, NIC, etc.

I really think this has something to do with Win 7 since I've never had troubles like this with XP.. where I would simply share a folder, set it up in XBMC to read that particular folder and it worked great. It sorta works connecting up to 7, but slow and choppy.

I can share the video between 2 Windows 7 machines and it runs the video fine.

Does anyone have any ideas what might help? I have no experience with Vista, nor have I run the Win 7 Beta.. so my experience with Win 7 style stuff is very new.

Does Ipv6 cause any problems with older routers and switches? there is a router, and 2 switches between the PC and the XB. again though, this has never had a single problem when the files were being shared from an XP machine.

Thanks.

are you running the latest drivers for your NIC?

also, make sure you are accessing the files on the PC through a straight smb share, not some sort of UPNP/DLNA server

Yeah, I'm running a straight SMB share.. as far as I know. I set it up similar to how I would have on XP.

I kinda ruled out the NIC drivers since I have 2 Win 7 machines with different drivers and both behave the same.

In XP, I remember having a problem where a video preview process (part of XP) read-locks multimedia files (avi, mp3, etc.) in order to generate realtime previews of the files in the Explorer window. The problem becomes more apparent if you open a single folder containing a large number of large *.avi files. There was some registry hacks that would disable the process, thus preventing the system from trying to generate those previews, and restore responsiveness to the system. I'm not sure if the same thing is happening in Windows 7, but it's certainly worth looking into. Good luck!

I did some rearranging of my network connections through various routers. If I plug my Win 7 PC into a 100MB router (WRT54G) instead of my gigabit router it works smooth. I am no networking expert.. but is it possible that the Win 7 default settings are too aggressive when transferring data from a machine hooked up to a gigabit switch.. and the end device can only handle 100MB?
