Some. A few links, only one of which sees enough drops for RED to make
eny difference at all. I've been remiss :-(, though oddly enough I've
spent some cycles with it last week, and have some more slotted this

If people are interested this link (unidirectionally) is doing RED'd:

8 (  80.247 ms  80.399 ms  80.463 ms
9 (  82.032 ms  81.574 ms  80.578 ms

BTW, if you want to have a numbers-based discussion of your
results, I suggest big-internet.

I suppose we need to come up with some good guidelines for tweaking
