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 ( 0.71 usr  0.65 sys +  0.00 cusr  0.00 csys =  0.00 CPU)

Test if the database has a query cache
Time for select_query_cache (10000): 82 wallclock secs ( 3.53 usr  0.98 sys +  0.00 cusr  0.00 csys =  0.00 CPU)

Time for select_query_cache2 (10000): 84 wallclock secs ( 3.50 usr  1.01 sys +  0.00 cusr  0.00 csys =  0.00 CPU)

Testing big selects on the table

Time for select_range (410:1057904): 230 wallclock secs ( 7.50 usr  5.11 sys +  0.00 cusr  0.00 csys =  0.00 CPU)
Time for min_max_on_key (70000): 155 wallclock secs (22.55 usr  6.20 sys +  0.00 cusr  0.00 csys =  0.00 CPU)
Time for count_on_key (50000): 349 wallclock secs (17.12 usr  4.59 sys +  0.00 cusr  0.00 csys =  0.00 CPU)

Testing count(distinct) on the table
Time for count_distinct_key_prefix (1000:1000): 41 wallclock secs ( 0.42 usr  0.13 sys +  0.00 cusr  0.00 csys =  0.00 CPU)
Time for count_distinct (1000:1000): 51 wallclock secs ( 0.44 usr  0.11 sys +  0.00 cusr  0.00 csys =  0.00 CPU)
Time for count_distinct_2 (1000:1000): 49 wallclock secs ( 0.41 usr  0.14 sys +  0.00 cusr  0.00 csys =  0.00 CPU)
Time for count_distinct_group_on_key (1000:6000): 47 wallclock secs ( 0.45 usr  0.14 sys +  0.00 cusr  0.00 csys =  0.00 CPU)
Time for count_distinct_group_on_key_parts (1000:100000): 75 wallclock secs ( 0.98 usr  0.61 sys +  0.00 cusr  0.00 csys =  0.00 CPU)
Time for count_distinct_group (1000:100000): 75 wallclock secs ( 0.97 usr  0.60 sys +  0.00 cusr  0.00 csys =  0.00 CPU)
Time for count_distinct_big (100:1000000): 80 wallclock secs ( 6.08 usr  6.96 sys +  0.00 cusr  0.00 csys =  0.00 CPU)
Total time: 1360 wallclock secs (65.68 usr 27.91 sys +  0.00 cusr  0.00 csys =  0.00 CPU)
