- Testing server 'MySQL 3.23.17 alpha' at 2000-06-01 3:46:46
- 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): 3 wallclock secs ( 0.64 usr 0.26 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 ( 0.12 usr 0.06 sys + 0.00 cusr 0.00 csys = 0.00 CPU)
- Time for select_range (410:1057904): 190 wallclock secs ( 8.49 usr 3.90 sys + 0.00 cusr 0.00 csys = 0.00 CPU)
- Time for min_max_on_key (70000): 210 wallclock secs (21.63 usr 3.48 sys + 0.00 cusr 0.00 csys = 0.00 CPU)
- Time for count_on_key (50000): 506 wallclock secs (17.66 usr 2.67 sys + 0.00 cusr 0.00 csys = 0.00 CPU)
- Time for count_group_on_key_parts (0:0): 0 wallclock secs ( 0.00 usr 0.00 sys + 0.00 cusr 0.00 csys = 0.00 CPU)
- Testing count(distinct) on the table
- Time for count_distinct (1000:2000): 110 wallclock secs ( 0.78 usr 0.10 sys + 0.00 cusr 0.00 csys = 0.00 CPU)
- Time for count_distinct_group_on_key (1000:6000): 58 wallclock secs ( 0.41 usr 0.03 sys + 0.00 cusr 0.00 csys = 0.00 CPU)

- Time for count_distinct_group (1000:100000): 75 wallclock secs ( 1.20 usr 0.44 sys + 0.00 cusr 0.00 csys = 0.00 CPU)
- Time for count_distinct_big (1000:10000000): 570 wallclock secs (73.95 usr 55.45 sys + 0.00 cusr 0.00 csys = 0.00 CPU)
