thanks for that test, good to see real numbers, otoh, floats only have a 
terrible performance if they are 'updated' (= receive a message.)

since there was already a good testlayout, I thought it might be worth 
to test the difference between s/r and cord connections. guess what. s/r 
were faster. I guess this is, because you need more cord connections to 
go from the random to the subpatch to the abstraction. but for me that 
was new. the overhead is not big, though, only around 10%.

but, sending messages in general (s/r of cord connections) is quite a 
bottleneck in pd and I wonder if that could be improved. This is where 
any other programming language wins :(.
