| Remote server minipc Ethernet 12 fps |
| Remote vnc/direct laptop Ethernet/tunnel 8 fps |
| Remote vnc/direct laptop Ethernet 8 fps |
| Remote vnc/direct minipc Ethernet/tunnel 8 fps |
| Remote vnc/direct minipc Ethernet 8 fps |
| Remote vnc/direct laptop WLAN/tunnel 8 fps |
| Remote vnc/direct laptop WLAN 8 fps |
| Remote server laptop WLAN/tunnel 6 fps |
| Remote server laptop WLAN 4 fps |
A preliminary conclusion tells us that the perfomance of the client-server render path strongly depends on the speed of the physical connection. Only with ethernet there is a significant advantage over standard vnc (where software rendering ist the default). A solution for remote rendering might be TurboVNC+VirtualGL on servers with GPUs.
