- Testing server 'MySQL 3.22.19a' at 1999-03-02 18:33:15
- 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): 35 wallclock secs (34.87 usr 0.00 sys + 0.00 cusr 0.00 csys = 0.00 CPU)
- Testing big selects on the table
- Time for select_big (70:17207): 4 wallclock secs ( 4.01 usr 0.00 sys + 0.00 cusr 0.00 csys = 0.00 CPU)
- Time for select_range (410:1057904): 592 wallclock secs (592.70 usr 0.00 sys + 0.00 cusr 0.00 csys = 0.00 CPU)
- Time for min_max_on_key (70000): 496 wallclock secs (495.60 usr 0.00 sys + 0.00 cusr 0.00 csys = 0.00 CPU)
- Note: Query took longer then time-limit: 600
- Estimating end time based on:
- 14250 queries in 2850 loops of 10000 loops took 601 seconds
- Estimated time for count_on_key (50000): 2108 wallclock secs (2107.58 usr 0.00 sys + 0.00 cusr 0.00 csys = 0.00 CPU)
- Estimated total time: 3235 wallclock secs (3234.82 usr 0.00 sys + 0.00 cusr 0.00 csys = 0.00 CPU)
