You remember when we promised to get back to you with a solution to the CPU overload due to macOS upgrade to the latest Sierra 10.12? It turned out that “ionodecache” process was the cause of the overload.
Good news is that Apple Team had fixed the bug
Update your macOS Sierra to the latest 10.12.1 version, share and access your remote devices with Flexihub and USB Network Gate. NO MORE CPU OVERLOAD!
