- Testing server 'MySQL 3.23.29a gamma' at 2000-12-24 7:26:42
- 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): 5 wallclock secs ( 1.03 usr 0.48 sys + 0.00 cusr 0.00 csys = 0.00 CPU)
- Testing big selects on the table
