Hi there

I/O performance is HIDEOUS when using a VM or external USB 3 device --I am experiencing huge Buffer refreshes in Plex media server when serving movies either from a VM running PLEX Media server or using external USB3 device on Windows.

Reverted back again to build 1511.

It only take me about 10 mins to restore so I'll keep the other image until the I/O problem is fixed

Could be VMWARE or USB 3 driver or PLEX.

Don't have time to debug all those products. !!!

1511 serving movies again fine --no buffering problems.

I have excellent Wifi - half the planet would DIE for ==>-up to 1 Gbs/s so no probs on that score !!
