Testing server 'MySQL 3.23.26 gamma' at 2000-10-13 15:53:40
Testing the speed of selecting on keys that consist of many parts
The test-table has 10000 rows and the test is done with 500 ranges.
Creating table
Inserting 10000 rows
Time to insert (10000): 7 wallclock secs ( 1.06 usr 1.39 sys + 0.00 cusr 0.00 csys = 0.00 CPU)
Testing big selects on the table
Time for select_big (70:17207): 1 wallclock secs ( 0.38 usr 0.19 sys + 0.00 cusr 0.00 csys = 0.00 CPU)
Time for select_range (410:1057904): 189 wallclock secs (26.94 usr 9.30 sys + 0.00 cusr 0.00 csys = 0.00 CPU)
Time for min_max_on_key (70000): 178 wallclock secs (29.56 usr 11.97 sys + 0.00 cusr 0.00 csys = 0.00 CPU)
Time for count_on_key (50000): 371 wallclock secs (20.88 usr 9.02 sys + 0.00 cusr 0.00 csys = 0.00 CPU)
Time for count_group_on_key_parts (1000:0): 41 wallclock secs ( 2.72 usr 0.84 sys + 0.00 cusr 0.00 csys = 0.00 CPU)
Testing count(distinct) on the table
Time for count_distinct (1000:2000): 74 wallclock secs ( 0.95 usr 0.28 sys + 0.00 cusr 0.00 csys = 0.00 CPU)
Time for count_distinct_group_on_key (1000:6000): 40 wallclock secs ( 0.63 usr 0.27 sys + 0.00 cusr 0.00 csys = 0.00 CPU)

Time for count_distinct_group (1000:100000): 149 wallclock secs ( 2.50 usr 1.00 sys + 0.00 cusr 0.00 csys = 0.00 CPU)
Time for count_distinct_big (1000:10000000): 1095 wallclock secs (227.86 usr 86.19 sys + 0.00 cusr 0.00 csys = 0.00 CPU)
