P51 freezing/stuttering under high network load

2018-01-22, 16:42 PM

Hello All!


I've bought Lenovo P51 recently. I upgraded Lenovo drivers, BIOS and installed all Microsoft updates. 
Within the last couple of days, I noticed that Windows 10 hangs (off and on) while accessing Windows shares on my local network.
The behavior I see is as follows:

  • Mouse movement is no longer smooth, jumping between locations versus gliding.
  • Applications (explorer and other) become unresponsive sporadically. It seems to affect just about everything...
  • The file copy window itself is also impacted, jumping in % versus advancing like normal and unresponsive sporadically.
  • Even BSOD happened once while the file was copying.
  • If I cancel the file copy the problem immediately goes away.

I chose a test file (about 170 GB) to do some testing with:

  • Copy from local SSD to the same SSD - no problems.
  • Copy from fileserver to SSD via Internal LAN Adapter (Intel 1Gbps) - problem occurs.
  • Copy from fileserver to SSD via External USB LAN Adapter (usb stick 1Gbps) - no problems.

All tests in Lenovo Vantage passes without any error.

Is anyone else experiencing a similar issue?

Thanks in advance!
