Testing server 'MySQL 3.23.37' at 2001-04-13 2:02:54
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 ( 0.80 usr 0.46 sys + 0.00 cusr 0.00 csys = 1.26 CPU)
Test if the database has a query cache
Time for select_query_cache (10000): 131 wallclock secs ( 3.58 usr 0.61 sys + 0.00 cusr 0.00 csys = 4.19 CPU)
Time for select_query_cache2 (10000): 131 wallclock secs ( 3.78 usr 0.68 sys + 0.00 cusr 0.00 csys = 4.46 CPU)
Testing big selects on the table

Testing count(distinct) on the table
Time for count_distinct_key_prefix (1000:1000): 56 wallclock secs ( 0.40 usr 0.05 sys + 0.00 cusr 0.00 csys = 0.45 CPU)
Time for count_distinct (1000:1000): 65 wallclock secs ( 0.34 usr 0.05 sys + 0.00 cusr 0.00 csys = 0.39 CPU)
Time for count_distinct_2 (1000:1000): 65 wallclock secs ( 0.36 usr 0.12 sys + 0.00 cusr 0.00 csys = 0.48 CPU)

Time for count_distinct_group (1000:100000): 190 wallclock secs ( 1.21 usr 0.35 sys + 0.00 cusr 0.00 csys = 1.56 CPU)
Time for count_distinct_big (100:1000000): 65 wallclock secs ( 7.60 usr 3.30 sys + 0.00 cusr 0.00 csys = 10.90 CPU)
Total time: 1999 wallclock secs (72.84 usr 16.51 sys + 0.00 cusr 0.00 csys = 89.35 CPU)
