Conclusion: X-Win32 outperforms VNC by a minimum factor of 5!
"VNC is doggishly slow."
Just about every VNC user we've come across at trade shows and elsewhere expresses this frustration with VNC's slow performance, whether it is RealVNC, UltraVNC, TightVNC, etc. Users also complain that VNC sessions clog the network and report that it is devoid of features like copy/paste, rootless X windows display, and OpenGL support.
Until recently, VNC was the only way to assure session persistency and session mobility. X-Win32 LIVE is a next-generation PC X server that obsoletes VNC with the fast speed of a state of the art X11 PC X server combined with session persistency, mobility and a host of features designed to make end-users more productive.X-Win32 LIVE lets you work at LAN-like speed from nearly anywhere over just about any kind of network connection. You'll be amazed how fast your sessions perform at Starbucks over WiFi.
As the chart below shows, X-Win32 LIVE matches VNC in all critical areas of session persistency and mobility. From there on X-Win32 leaves VNC in the dust in terms of performance, security, ease of use and productivity-enhancing features.
