Yes, this IS a complicated question. Not because it is "technicaly
complicatd" but because "many factors affect it".
If you use "setblk 0", you are using "Variable Blocksize". Which
just makes it more complicated to calculate the throughput, since
there is no way for you to know what block size will be under use
in a given moment.
But I'll give you the benefit of the doubt. Since you say it is not
a complicated issue, please give us the throughput he is getting
for this DLT Unit.
