Ricky Posted October 8, 2017 Share #1 Posted October 8, 2017 (edited) I use VMWare Workstation 12 on Windows 10, I can see network interface is 1Gbps in DSM which installed in VM. But it's very slow copy file between host machine and DSM, about 20MB/s~30MB/s, I use bridge network. Any one have this issue? Thanks.

Ricky Posted October 23, 2017 Author Share #3 Posted October 23, 2017 I moved VM to Virtualbox and network transfer speed up to 30M/s but still poor performance, also tested use a individual Intel network interface got the same speed. Any one has this problem? Quote Link to comment Share on other sites More sharing options...
