The people who know what helps are the ones who have been setting the
Internet land speed records. They typically use frames larger than 1500.
As for the principal issue, well, if there are several factors that will
contribute to solving the problem, I think that you get better results
if you attack all of them in parallel. Then, if you learn that there
really is one principal factor and you need some management approval to
move on that issue, you will have laid the groundwork for making a
business case because you've already done all the other things.=20
