Hey Jens,

Just to give some more feedback/measurements to this. I did some quick tests to find out the difference between these calls. I tested the following two calls, each 1.000.000 times:

protocol.GetParameter(101)

protocol.GetParameters(new uint[]{101})

The first loop took about 21 seconds, the second one took 32 seconds.
It seems to be 30% faster to use the first call. Do note that this difference is negligible when doing a moderate amount of calls.
