- Testing server 'MySQL 3.23.31' at 2001-12-17 13:31:13
- 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): 4 wallclock secs ( 0.76 usr 0.67 sys + 0.00 cusr 0.00 csys = 0.00 CPU)
- Testing big selects on the table
