Testing server 'MySQL 3.23.25 beta' at 2000-09-27 4:36:14
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 ( 1.25 usr 1.03 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 ( 0.44 usr 0.11 sys + 0.00 cusr 0.00 csys = 0.00 CPU)
Time for select_range (410:1057904): 187 wallclock secs (27.56 usr 9.31 sys + 0.00 cusr 0.00 csys = 0.00 CPU)
Time for min_max_on_key (70000): 197 wallclock secs (30.55 usr 11.14 sys + 0.00 cusr 0.00 csys = 0.00 CPU)
Time for count_on_key (50000): 402 wallclock secs (22.42 usr 8.89 sys + 0.00 cusr 0.00 csys = 0.00 CPU)
Time for count_group_on_key_parts (1000:0): 47 wallclock secs ( 2.34 usr 0.75 sys + 0.00 cusr 0.00 csys = 0.00 CPU)
Testing count(distinct) on the table
Time for count_distinct (1000:2000): 97 wallclock secs ( 0.97 usr 0.36 sys + 0.00 cusr 0.00 csys = 0.00 CPU)
Time for count_distinct_group_on_key (1000:6000): 54 wallclock secs ( 0.61 usr 0.23 sys + 0.00 cusr 0.00 csys = 0.00 CPU)

Time for count_distinct_group (1000:100000): 144 wallclock secs ( 2.70 usr 0.98 sys + 0.00 cusr 0.00 csys = 0.00 CPU)
Time for count_distinct_big (1000:10000000): 1117 wallclock secs (225.77 usr 83.39 sys + 0.00 cusr 0.00 csys = 0.00 CPU)
