- Testing server 'PostgreSQL 6.4' at 1999-03-11 13:25:07
- 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
- Time for book-keeping (1): 0 wallclock secs ( 0.00 usr 0.00 sys + 0.00 cusr 0.00 csys = 0.00 CPU secs)
- Inserting 10000 rows
- Time to insert (10000): 33 wallclock secs ( 6.05 usr 0.57 sys + 0.00 cusr 0.00 csys = 0.00 CPU secs)
- Time for book-keeping (1): 1 wallclock secs ( 0.00 usr 0.00 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 ( 0.20 usr 0.01 sys + 0.00 cusr 0.00 csys = 0.00 CPU secs)
- Time for select_range (410:24731): 11 wallclock secs ( 0.50 usr 0.02 sys + 0.00 cusr 0.00 csys = 0.00 CPU secs)
- Time for min_max_on_key (70000): 461 wallclock secs (17.09 usr 1.94 sys + 0.00 cusr 0.00 csys = 0.00 CPU secs)
- Note: Query took longer then time-limit: 600
- Estimating end time based on:
- 18630 queries in 3726 loops of 10000 loops took 601 seconds
- Estimated time for count_on_key (50000): 1612 wallclock secs (28.56 usr 3.19 sys + 0.00 cusr 0.00 csys = 0.00 CPU secs)
- Time for book-keeping (1): 0 wallclock secs ( 0.00 usr 0.00 sys + 0.00 cusr 0.00 csys = 0.00 CPU secs)
- Estimated total time: 2120 wallclock secs (52.41 usr 5.73 sys + 0.00 cusr 0.00 csys = 0.00 CPU secs)
