Comment (by Dhalgren):
attached rest of the slice histograms
times in seconds for each are
00 5.697
01 5.615
02 5.625
03 5.556
04 5.567
05 5.574
06 7.137
07 3.666
can provide grep extracts or entire log
recalling I saw this on 0.2.9.14 so probably not a (recent) regression or
KIST
guess is event loop is not blocking rather than some function hogging CPU,
but just a guess; performance browsing through exit is fine when this
happens
