What is the server side cost of UltraVNC ?

[flonou]

Hello,

At work, we are managing a big experimental immersive platfrom with a cluster of 13 computers. In this setup, one key element is latency between inputs and display. We need to keep this latency on the computers of our cluster as low as possible to have the best immersion possible. For example, adding a full frame latency (16ms at 60hz) to the global latency is significant for us
My question is : What computer resources does UltraVNC server use and will the latency between input and display rise when idle and when used for remote access ?

Thanks
