- Testing server 'MySQL 3.22.18' at 1999-02-27 21:17:16
- Testing the speed of selecting on keys that consist of many parts
- The test-table has 10000 rows and the test is done with 22 ranges.
- Creating table
- Inserting 10000 rows
- Time to insert (10000): 5 wallclock secs ( 1.45 usr 0.33 sys + 0.00 cusr 0.00 csys = 0.00 CPU secs)
- Testing big selects on the table
- Time for select_big (70:17207): 1 wallclock secs ( 0.24 usr 0.09 sys + 0.00 cusr 0.00 csys = 0.00 CPU secs)
- Time for select_range (410:127625): 9 wallclock secs ( 1.84 usr 0.61 sys + 0.00 cusr 0.00 csys = 0.00 CPU secs)
- Time for min_max_on_key (70000): 195 wallclock secs (33.98 usr 4.55 sys + 0.00 cusr 0.00 csys = 0.00 CPU secs)
- Note: Query took longer then time-limit: 600
- Estimating end time based on:
- 45510 queries in 9102 loops of 10000 loops took 601 seconds
- Estimated time for count_on_key (50000): 660 wallclock secs (26.15 usr 3.48 sys + 0.00 cusr 0.00 csys = 0.00 CPU secs)
- Estimated total time: 870 wallclock secs (63.67 usr 9.06 sys + 0.00 cusr 0.00 csys = 0.00 CPU secs)
