- Testing server 'MySQL 3.23.29 gamma' at 2000-12-17 7:33:18
- 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): 41 wallclock secs ( 7.98 usr 5.98 sys + 0.00 cusr 0.00 csys = 0.00 CPU)
- Testing big selects on the table
- Time for select_big (70:17207): 7 wallclock secs ( 1.74 usr 1.19 sys + 0.00 cusr 0.00 csys = 0.00 CPU)
- Note: Query took longer then time-limit: 600
- Estimating end time based on:
- 205 queries in 5 loops of 10 loops took 659 seconds
- Estimated time for select_range (410:537457): 1318 wallclock secs (116.36 usr 78.78 sys + 0.00 cusr 0.00 csys = 0.00 CPU)
- Note: Query took longer then time-limit: 600
- Estimating end time based on:
- 32291 queries in 4613 loops of 10000 loops took 601 seconds
- Estimated time for min_max_on_key (70000): 1302 wallclock secs (180.73 usr 74.07 sys + 0.00 cusr 0.00 csys = 0.00 CPU)
- Note: Query took longer then time-limit: 600
- Estimating end time based on:
- 11240 queries in 2248 loops of 10000 loops took 601 seconds
- Estimated time for count_on_key (50000): 2673 wallclock secs (132.65 usr 51.65 sys + 0.00 cusr 0.00 csys = 0.00 CPU)
- Time for count_group_on_key_parts (1000:100000): 303 wallclock secs (12.11 usr 7.43 sys + 0.00 cusr 0.00 csys = 0.00 CPU)
- Testing count(distinct) on the table
- Note: Query took longer then time-limit: 600
- Estimating end time based on:
- 1486 queries in 743 loops of 1000 loops took 601 seconds
- Estimated time for count_distinct (2000:1486): 808 wallclock secs ( 6.35 usr 2.11 sys + 0.00 cusr 0.00 csys = 0.00 CPU)
- Time for count_distinct_group_on_key (1000:6000): 373 wallclock secs ( 3.78 usr 1.54 sys + 0.00 cusr 0.00 csys = 0.00 CPU)
- Note: Query took longer then time-limit: 600
- Estimating end time based on:
- 431 queries in 431 loops of 1000 loops took 601 seconds
- Estimated time for count_distinct_group_on_key_parts (1000:43100): 1394 wallclock secs (12.62 usr 7.80 sys + 0.00 cusr 0.00 csys = 0.00 CPU)
- Note: Query took longer then time-limit: 600
- Estimating end time based on:
- 432 queries in 432 loops of 1000 loops took 601 seconds
- Estimated time for count_distinct_group (1000:43200): 1391 wallclock secs (12.41 usr 7.94 sys + 0.00 cusr 0.00 csys = 0.00 CPU)
- Time for count_distinct_big (100:1000000): 333 wallclock secs (93.16 usr 74.12 sys + 0.00 cusr 0.00 csys = 0.00 CPU)
- Estimated total time: 9945 wallclock secs (579.92 usr 312.63 sys + 0.00 cusr 0.00 csys = 0.00 CPU)
