I have a vendor telling me that I should round-robin the paths on my control unit add statements. Something about that it provides a different first path for each control unit which can improve performance.
Like this... cunumbr=0,path=(0,1,2,3,4,5) cunumbr=1,path=(1,2,3,4,5,0) cunumbr=2,path=(2,3,4,5,0,1) cunumbr=3,path=(3,4,5,0,1,2) cunumbr=4,path=(4,5,0,1,2,3) instead of simply like this.... cunumbr=0,path=(0,1,2,3,4,5) cunumbr=1,path=(0,1,2,3,4,5) cunumbr=2,path=(0,1,2,3,4,5) cunumbr=3,path=(0,1,2,3,4,5) cunumbr=4,path=(0,1,2,3,4,5) Actually, he wasn't sure about it, but said he had others that swore by it and so figured it couldn't hurt. Personally I think it makes it harder to read, but if there is actually a performance benefit... Anyone know if there is any truth to this? Or if it used to be true but no longer applies? We've never done the round-robin thing.
