Windows 10: Slow Network Speed During File Transfer Unless Gaming

Frm: Windows 10, Asus Maximus III MoBo. Realtek Gig Network. Windows or Asus mb drivers, not sure.

Through: Linksys gig switch to netgear gig switch

To: Dell R710 with gig cards running Vsphere 6, to a default VM (1 cpu, 2 gigs ram) running CentOS 7.2

using Cygwin to use scp to transfer large (3 gigs or so each) files to a VM. scp -r * to a CIFS volume on the VM.

starts at 40 mb/s and slowly drops to 5 mb/s.

oddly, if I bring up Steam and play Doom II (old Dosbox game) my transfer kicks up to 80 mb/s. Rocksmith only gets to 65 mb/s and Carmageddon Reincarnation gets to 75 mb/s.

If I exit the game entirely, the speed slows back down to 5 mb/s until I start up a game.

I imagine it's something to do with the games taking over the system but it is puzzling.

Original Title: Slow file transfer speeds

I am getting 1Mb/s transfer speeds when copying a file from a windows 10 machine to a windows 7 machine, both machines are on a gigabit network and are running a 1 Gb/s.

any ideas what may be causing this. it started when I installed my windows 10.
