Testing server 'MySQL 3.23.29a gamma' at 2000-12-17 3:21:10
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): 6 wallclock secs ( 1.03 usr 0.81 sys + 0.00 cusr 0.00 csys = 1.84 CPU)
Testing big selects on the table
Time for select_big (70:17207): 2 wallclock secs ( 0.26 usr 0.27 sys + 0.00 cusr 0.00 csys = 0.53 CPU)
Time for select_range (410:1057904): 326 wallclock secs (17.61 usr 17.05 sys + 0.00 cusr 0.00 csys = 34.66 CPU)
Time for min_max_on_key (70000): 292 wallclock secs (28.50 usr 13.56 sys + 0.00 cusr 0.00 csys = 42.06 CPU)
Note: Query took longer then time-limit: 600
Estimating end time based on:
45085 queries in 9017 loops of 10000 loops took 601 seconds
Estimated time for count_on_key (50000): 666 wallclock secs (20.47 usr 9.08 sys + 0.00 cusr 0.00 csys = 29.56 CPU)
Time for count_group_on_key_parts (1000:100000): 85 wallclock secs ( 1.82 usr 1.89 sys + 0.00 cusr 0.00 csys = 3.71 CPU)
Testing count(distinct) on the table
Time for count_distinct (2000:2000): 217 wallclock secs ( 0.98 usr 0.30 sys + 0.00 cusr 0.00 csys = 1.28 CPU)
Time for count_distinct_group_on_key (1000:6000): 101 wallclock secs ( 0.58 usr 0.35 sys + 0.00 cusr 0.00 csys = 0.93 CPU)
Time for count_distinct_group_on_key_parts (1000:100000): 228 wallclock secs ( 2.00 usr 1.90 sys + 0.00 cusr 0.00 csys = 3.90 CPU)
Time for count_distinct_group (1000:100000): 229 wallclock secs ( 1.96 usr 1.95 sys + 0.00 cusr 0.00 csys = 3.91 CPU)
Time for count_distinct_big (100:1000000): 48 wallclock secs (16.66 usr 15.02 sys + 0.00 cusr 0.00 csys = 31.68 CPU)
Estimated total time: 2200 wallclock secs (91.87 usr 62.18 sys + 0.00 cusr 0.00 csys = 154.06 CPU)
