(My) Fix for slow folder browsing

[parkaboy]

Hi,

A while ago I moved all of my media files to a Synology NAS. Before, they were stored locally on the same PC I'd run UMS on. Folder and file browsing in UMS (and PMS, for that matter) became annoyingly, unusably slow after the switch to NAS. Googling the issue yielded no results. In the end I figured out how to fix it on my own. Been meaning to post that fix just in case it helps others.

To be clear, this is simply what worked for me. If it helps others, great. If not, too bad. I'm not going to monitor this thread to help others troubleshoot -- I'm not that involved.

So again, the symptons: file/folder browsing becomes incredibly slow after moving media files to NAS. The NAS is NOT doing the media-serving; that's being done by UMS (or PMS) on a separate PC in the network.

The fix: enable SMB large MTU on both the media-serving PC and on the NAS.

To do so on a PC running Windows 7, apply this registry tweak: http://cpeel.livejournal.com/96393.html. Log off/on or reboot afterwards.

To enable this setting on a Synology NAS, open up the Control Panel in DSM (Disk Station Manager) and click the 'Win/Mac/NFS' option under 'File Sharing and Privileges'. In the window that pops up, under the 'Windows File Service' tab, make sure the 'Enable SMB 2 and Large MTU' box is checked. Apply & Save changes.

If you're running a different OS or another version of Windows, or your NAS is a different brand, you'll have to google around to determine whether or not this tweak has relevance to you. Searching for 'enable SMB large MTU' + NAS model / OS version should yield relevant results.

Hope it helps at least someone.
