Looking for feedback about El Capitan's SMB performance. At my workplace, we have a dozen Macs on a Windows network. Yosemite's SMB performance is jaw-droppingly bad with our Windows 2012 R2 file servers. It takes 2-3 minutes to list a directory with a few dozen files in it. Copy speeds are terrible. PCs are fine. Older Macs and OS X are fine. Seems to be specifically Yosemite when talking to Windows 2012. I spoke to Apple support and was escalated to an engineering guy who more or less admitted it's a known issue and he hinted that it would be resolved in El Capitan (didn't promise or say it outright though.) I'm hoping to hear that it's fixed and browsing SMB file shares on Windows 2012 servers isn't as slow as it is on Yosemite.
