Finally got to trying an 8.x running on my Linux (SuSE) w/display
on Windows 7SP1 (64bit) using Cygwin's Xserver.

I guess vim isn't using the win10-only terminal functions since it is
working on Win7

For speed testing, I did a full ls listing of /usr/lib64 w/6917 entries and
used 'dd' to sync. In bash, I used it's time function (and format:
TIMEFORMAT="%2Rsec %2Uusr %2Ssys (%P%% cpu)" ).
ran the whole thing under " bash -c 'cmd'":

time bash -c 'ls --quoting-style=literal --show-control-chars
--color=always -lgG /usr/lib64|dd oflag=dsync'

So besides the color output in the terminal window (TERM=xterm-256color),
I got 2 timings:
1164+1 records in
1164+1 records out
596002 bytes (596 kB, 582 KiB) copied, 3.49621 s, 170 kB/s
3.51sec 0.04usr 0.05sys (2.60% cpu)

So about a 17 million baud equivalent (this is over my 8Gb ethernet link).



I'd try a different X-server and I assume you have a 1Gb wired connection?

Best of luck!
