Today I tested desktop sharing on my local network between two machines:
1. Acer Travel Mate 5720 (some Intel 3,6GHz) - Intel onboard 1280x800
2. AMD (as described in my other posting today on CPU usage) ATI graphic 1920x1080
3. Local LAN in between (wireless involved)
Though image quality is excellent - latency on the shared desktop is about 3-5 sec, rendering it completely useless - even for myself who knows that I have to wait.(clicking and typing in the other direction seems to be faster - so it gets out of sync with the images)
The CPU usage of the machine serving the screen shoots up into the 90ies.(both ways) Latency for sound coming from the AMD machine goes up to 10sec while the other way around there is hardly any sound latency. This is even the case when the Intel machine serves the screen and the AMD is only watching.
Turning off Desktop sharing lets the situation stay the same: 71% CPU - latency a couple of seconds - for now audio only.
One observation: the AMD CPU steps up its speed from 800.000 to 1900.000 (accompanied by surging fan speed) - and stays that way for many minutes. I'm not sure what this means for interpreting the top-command: is 71% on 1900.000 around twice as much CPU cycles as 71% on 800.000??
I've tested for about 25 minutes.
Is there any help with that? I'm not using neither outdated nor toy- hardware. (actually I upgraded my hardware to run SC properly)
How could I analyze this further?
