Mac OSX 10.6.7 slow to read smb file shares
We have integrated a hundred Macs into our network. When ever a Mac tries to read a directory on a Windows 2003 R2 file share or Windows 2008, it takes an inordinate amount of time. Even listing a simple sub-directory with just 3 1K files in it can take upwards of a minute.
Now we installed an afp file share and speed is dramatically faster under exact same testing conditions.
But of course we are a Windows and Linux shop running AD. And even if we bought three or four Mac Pros and set up afp file shares, we'd have no way to manage them.
This problem of slow smb directory and file listing is driving us crazy. We have tested for months, replaced a core switch, tested and replaced cables, new N AP. All work perfectly with Windows client. No delays etc. Even simultaneously with Macs and Windows laptops, Windows machines are fine.
Any suggestions, we are going crazy?
