Look carefully at the following (genuine) extract
from a 9.0.1.3 trace file, and examine the TIM=
entries:

PARSING IN CURSOR #2 len=210 dep=1 uid=0 oct=3 lid=0
tim=1019495629365212 hv=787810128 ad='6e0a278'
select /*+ rule */ bucket_cnt, row_cnt, cache_cnt, null_cnt,
timestamp#, sample_size, minimum, maximum, distcnt, lowval, hival,
density, col#, spare1, spare2, avgcln from hist_head$ where obj#=:1
and intcol#=:2
END OF STMT
PARSE
#2:c=0,e=492,p=0,cr=0,cu=0,mis=0,r=0,dep=1,og=3,tim=1019495629365100


Note how Oracle has managed to finish parsing the
statement 112 microseconds before it started.

Now that's how to pass a benchmark !
