Network latency

Since upgrading to 10.0.10586 a couple of days ago, opening files from network has become extremely sluggish. Nothing on the network side has changed, same router, same switches, same NAS. Previously, this machine was on XP SP3 and everything I clicked on opened instantaneously from 1 mb xls to 2 gb mp4. Now, when I try to open something on the network it just grinds away for what feels like an eternity.

i5-3570k @4.1Ghz
8 GB Ram
Samsung 830
Onboard Broadcom NIC

Any ideas?

That's probably not network latency. Network latency is how long the low level network packets are delayed, and there is no indication that this problem is at a low level.

More than likely, given the age of your previous system (XP) your NAS is probably likewise older which means it probably doesn't support the latest SMB protocols fully. You might look to see if your NAS has an upgrade available for it.

My system is a i5-3570k @4.1Ghz on an Asrock Z77. Not sure if that qualifies as old or not. The NAS is a Synology DS1515+ with the latest DSM.
My NAS is running smbd 4.1.20:

Code:

admin@DS1515:/$ smbd -V
Version 4.1.20
Synology Build 7321, May  4 2016 11:48:34

Samba 4.1.20 was released on 9/1/15, so it's not that old.
