Hi Casey,

See inline replies.

Are you sure you are using x11vnc rather than one of 4 implementations of Xvnc?

(x11vnc shares out a local display, while Xvnc is a display that can
only be accessed over VNC. Xvnc is typically launched via the
vncserver script.)

If so, are you sharing out the local display, a Xdummy display, or an
Xvfb display?

I tested out Ubuntu 14.04's version of x11vnc with its local display,
(and with TigerVNC Client for Windows 1.4.3) and I can confirm it is
indeed not very snappy. In particular, it is sluggish to move windows
x11vnc -unixpw -display WAIT:cmd=FINDCREATEDISPLAY

I then tested out the best general-purpose implementation of Xvnc,
TigerVnc 1.4.3, and it was significantly more snappy, including for
moving windows around.
vncserver -autokill -SecurityTypes=VeNCrypt,TLSPlain -PlainUsers=$USER
-pam_service login -desktop $HOSTNAME +extension GLX

Yes it would work well. Compared to TigerVNC, no. Compared to x11vnc, yes.

However, X2Go has other benefits that might interest you such as:
seamless window mode (single application mode)
published apps
easier session mangement (no need to manually start VNC server)
sound (uncompressed, but that's fine for gigabit)
folder sharing
