Testing server 'MySQL 3.23.17a alpha' at 2000-06-02 19:10:01
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 ( 1.27 usr 1.42 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 ( 0.39 usr 0.11 sys + 0.00 cusr 0.00 csys = 0.00 CPU)
Time for select_range (410:1057904): 185 wallclock secs (27.20 usr 8.77 sys + 0.00 cusr 0.00 csys = 0.00 CPU)
Time for min_max_on_key (70000): 161 wallclock secs (31.55 usr 12.17 sys + 0.00 cusr 0.00 csys = 0.00 CPU)
Time for count_on_key (50000): 321 wallclock secs (21.41 usr 8.33 sys + 0.00 cusr 0.00 csys = 0.00 CPU)
Time for count_group_on_key_parts (1000:0): 34 wallclock secs ( 2.64 usr 1.00 sys + 0.00 cusr 0.00 csys = 0.00 CPU)
Testing count(distinct) on the table
Time for count_distinct (1000:2000): 69 wallclock secs ( 1.17 usr 0.41 sys + 0.00 cusr 0.00 csys = 0.00 CPU)
Time for count_distinct_group_on_key (1000:6000): 38 wallclock secs ( 0.70 usr 0.17 sys + 0.00 cusr 0.00 csys = 0.00 CPU)
