Hm, I've not personally observed that in my test cluster, or at least
not noticed anything out of line.

"Significantly" slower is bad; we mandate that "DC or not DC" is _not_
the question, and that users shouldn't care about this designation.

Could anyone who reproduces this report a few more details? Is it the
local node, the time it takes to process on the DC, or the network
roundtrip? (Should be observable using tcpdump/wireshark)
