Fine which makes it an interesting data point and something to look
at after lunch when I'm not doing something else kinda issue. Not
something I'm going to treat as a P1 and drop everything work or real
life related for. I'm not say it shouldn't be looked it, just that in
the grand scheme of the thing its not a huge issue. Kinda like when
people feel the need to tune IGP time sub second convergence but do
impactful maint on routers or circuits 3-4 times a yr. If you lock
the doggie door but leave the front door open the bad guys can walk
right in. :)
