SMB issues from a mac

[damonwilson24]

I am having issues with my macs opening up smb folders that are very large (specifically my photo backups).  It will eventually open, but it takes a very long time and makes my photos share unusable from my mac.  My windows pc opens it right up.  I do not have any issue opening up smaller SMB shares from the mac.  Aside from creating a lot of subfolders for my pictures, are they any other options?  Is this a known limitation?  For the record I am running Yosemite.
