- Testing server 'MySQL 3.22.16 gamma' at 1999-02-07 13:47:07
- Testing the speed of selecting on keys that consist of many parts
- The test-table has 10000 rows and the test is done with 8.5 ranges.
- Creating table
- Inserting 10000 rows
- Time to insert (10000): 18 secs (17.89 usr 0.00 sys = 17.89 cpu)
- Testing big selects on the table
- Time for select_big (70:17207): 3 secs ( 2.81 usr 0.00 sys = 2.81 cpu)
- Time for select_range (400:61130): 12 secs (11.82 usr 0.00 sys = 11.82 cpu)
- Time for min_max_on_key (70000): 261 secs (261.04 usr 0.00 sys = 261.04 cpu)
- Note: Query took longer then time-limit: 600
- Estimating end time based on:
- 42345 queries in 8469 loops of 10000 loops took 601 seconds
- Estimated time for count_key (50000): 709 secs (709.52 usr 0.00 sys = 709.52 cpu)
- Estimated total time: 1003 secs (1003.10 usr 0.00 sys = 1003.10 cpu)
