Q: File Transfers slow between two iMac 5K Retina Macs on same network
I have been looking for a few weeks for a solution to my slow network file transfers between two new iMac 5K Retina Macs. They both are high-configured and only have SSD storage. They run OS X Yosemite 10.10.1 and all other updates are current. I have tried via ethernet and wi-fi (type N) and get about the same results. The worst part is I have 30+ mbps internet speed and I can download a huge file quicker than I can copy it between two $4K Macs!!!!. The speed is about 1-2MBytes/sec. If I copy a folder with say 1.5GB in 7 files it takes 16 mins or so.
I have tried afp://, smb://, cifs:// protocols and all are slow.
My previous iMacs and MacBook Pros with Snow Leopard never had this issue.
Any suggestions?
OS X Yosemite (10.10.1), iPhone 6 Plus, iPad Gen 4
