Not here. Haven't got the time to test it thoroughly yet but so far SMB seems to be WAY better than 10.9.1 on my late 2012 Mac Mini. As in I can actually save files over SMB nowfrom my Windows 7 virtual machines in VMWare Fusion on another Mac (iMac mid-2011, now also with 10.9.2) and don't have to go by my QNAP NAS as an intermediary.
Agreed. Access to my WD Mybook live is fast! Used to be so slow finder would crash. While my Windows VMs would run tip top. So happy this has finally been sorted.
Thank you Apple.
