Testing server 'MySQL 3.23.22 beta' at 2000-08-17 18:22:00
Testing the speed of selecting on keys that consist of many parts
The test-table has 10000 rows and the test is done with 12 ranges.
Creating table
Inserting 10000 rows
Time to insert (10000): 4 wallclock secs ( 0.81 usr 0.43 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 ( 0.13 usr 0.06 sys + 0.00 cusr 0.00 csys = 0.00 CPU)
Time for select_range (410:75949): 2 wallclock secs ( 0.65 usr 0.32 sys + 0.00 cusr 0.00 csys = 0.00 CPU)
Time for min_max_on_key (70000): 205 wallclock secs (20.60 usr 3.98 sys + 0.00 cusr 0.00 csys = 0.00 CPU)
Time for count_on_key (50000): 518 wallclock secs (16.08 usr 3.16 sys + 0.00 cusr 0.00 csys = 0.00 CPU)
Time for count_group_on_key_parts (1000:0): 61 wallclock secs ( 1.09 usr 0.27 sys + 0.00 cusr 0.00 csys = 0.00 CPU)
Testing count(distinct) on the table
Time for count_distinct (1000:2000): 124 wallclock secs ( 0.65 usr 0.16 sys + 0.00 cusr 0.00 csys = 0.00 CPU)
Time for count_distinct_group_on_key (1000:6000): 64 wallclock secs ( 0.37 usr 0.07 sys + 0.00 cusr 0.00 csys = 0.00 CPU)
Time for count_distinct_group_on_key_parts (1000:100000): 77 wallclock secs ( 0.93 usr 0.45 sys + 0.00 cusr 0.00 csys = 0.00 CPU)
Time for count_distinct_group (1000:100000): 77 wallclock secs ( 0.94 usr 0.33 sys + 0.00 cusr 0.00 csys = 0.00 CPU)
Time for count_distinct_big (1000:10000000): 559 wallclock secs (69.04 usr 55.99 sys + 0.00 cusr 0.00 csys = 0.00 CPU)
Total time: 1692 wallclock secs (111.29 usr 65.22 sys + 0.00 cusr 0.00 csys = 0.00 CPU)
