- Testing server 'MySQL 3.22.16 gamma' at 1999-02-20 21:28:50
- 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): 12 wallclock secs ( 2.52 usr + 1.26 sys = 3.79 CPU)
- Testing big selects on the table
- Time for select_big (70:17207): 1 wallclock secs ( 0.23 usr + 0.11 sys = 0.34 CPU)
- Time for select_range (400:61130): 5 wallclock secs ( 1.21 usr + 0.42 sys = 1.63 CPU)
- Time for min_max_on_key (70000): 216 wallclock secs (49.80 usr + 13.51 sys = 63.31 CPU)
- Note: Query took longer then time-limit: 600
- Estimating end time based on:
- 45135 queries in 9027 loops of 10000 loops took 601 seconds
- Estimated time for count_key (50000): 665 wallclock secs (36.67 usr + 9.66 sys = 46.33 CPU)
- Estimated total time: 899 wallclock secs (90.43 usr + 24.97 sys = 115.41 CPU)
