- Testing server 'MySQL 3.22.18' at 1999-03-07 23:24:05
- Testing the speed of selecting on keys that consist of many parts
- The test-table has 10000 rows and the test is done with 1.5 ranges.
- Creating table
- Inserting 10000 rows
- Time to insert (10000): 5 wallclock secs ( 1.55 usr 0.28 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 ( 0.17 usr 0.08 sys + 0.00 cusr 0.00 csys = 0.00 CPU secs)
- Time for select_range (410:24731): 2 wallclock secs ( 0.43 usr 0.11 sys + 0.00 cusr 0.00 csys = 0.00 CPU secs)
- Time for min_max_on_key (70000): 30 wallclock secs (14.91 usr 1.84 sys + 0.00 cusr 0.00 csys = 0.00 CPU secs)
- Time for count_on_key (50000): 592 wallclock secs (25.52 usr 3.32 sys + 0.00 cusr 0.00 csys = 0.00 CPU secs)
- Total time: 630 wallclock secs (42.58 usr 5.63 sys + 0.00 cusr 0.00 csys = 0.00 CPU secs)
