All regressions (save for zone-balancing-batching) are well in the
noise: I just ran qsbench and it seems to have a large variation of
elapsed time:
$ export TIMEFORMAT="%3R %3S %3U"
$ for i in $(seq 1 7) ;do time ./qsbench -m 350 ;done
106.770 2.834 24.404
111.041 2.975 24.130
108.535 2.796 24.214
108.676 2.894 24.181
109.222 2.719 24.407
114.044 2.878 24.155
108.514 2.801 24.340
Probably tests should be ran with -s option.
Nikita.
