Jonathan Gray commented on HBASE-80:
------------------------------------
Very odd result...
Random writes: Timer for 10000 and cols 7 = 4062 ms
Random reads: Timer for 100 and size 7 = 105 ms
Random writes: Timer for 10000 and cols 8 = 3995 ms
Random reads: Timer for 100 and size 8 = 4024 ms
Going from 7 columns in the family to 8 columns leads to 40x slowdown.
Rebalancing of some sortedmap or hashmap or something on the way out?
