I set 0.05.

I need short time frames for visually smooth interaction, both with 
externally and internally clocked events. Example of external events

Here, I'm throttling at 20ms. Lag in human interaction devices is 
extremly frustrating. You overshoot, then undershoot the desired 
value. The closed loop action - visual feedback requires this kind of 
speed.

Scripted simulations should give a visual feedback as smooth as 
possible for internal clocks also. In-world (prim) controllers 
relying on a continous flow of touch() event are throttled at 50ms. 
Higher throttle would result in jerky movement.

This is an experimental grid and I don't care high runtimes. We have 
astronomy simulations where visitors control telescopes and 
spectrometers, and some nuclear labs for school, and nobody lags up 
to now.

Unfortunately, I can't afford Windows servers so I have to deal with 
MONO jitterish clock. That was a surprise to me to discover the 
difference.

Not all grids are social/residential. OpenSim should not be 
restricted to this framework. It is desirable to push the limits. 
They may be higher that you think.
