[Opensim-users] Scripting: 10x speed boost with C#

[Neil Canham]

It is in OpenSim.ini -

    ScriptDelayFactor = 0.0

I wasn't aware of it until this thread - so thanks for making me aware - it
has speeded up a number of scripts for me - of course, the delays are
required in public sims where griefing might be an issue, but for private
installations, can anyone see any reason not to set that to zero?  I guess
there might be scripts that are 'accidentally' working by relying on the
delays, but other than that, no fundamental opensim architectural reason?
