- Testing server 'Access 2000' at 2000-01-04 0:50:34
- Testing the speed of selecting on keys that consist of many parts
- The test-table has 10000 rows and the test is done with 45.5 ranges.
- Creating table
- Inserting 10000 rows
- Time to insert (10000): 69 wallclock secs (68.33 usr 0.00 sys + 0.00 cusr 0.00 csys = 0.00 CPU)
- Testing big selects on the table
- Time for select_big (70:17207): 4 wallclock secs ( 3.96 usr 0.00 sys + 0.00 cusr 0.00 csys = 0.00 CPU)
- Time for select_range (410:248587): 63 wallclock secs (63.11 usr 0.00 sys + 0.00 cusr 0.00 csys = 0.00 CPU)
- Note: Query took longer then time-limit: 600
- Estimating end time based on:
- 37233 queries in 5319 loops of 10000 loops took 601 seconds
- Estimated time for min_max_on_key (70000): 1129 wallclock secs (1129.48 usr 0.00 sys + 0.00 cusr 0.00 csys = 0.00 CPU)
- Time for count_on_key (50000): 445 wallclock secs (445.17 usr 0.00 sys + 0.00 cusr 0.00 csys = 0.00 CPU)
- Estimated total time: 1710 wallclock secs (1710.98 usr 0.00 sys + 0.00 cusr 0.00 csys = 0.00 CPU)
