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):  7 wallclock secs ( 1.27 usr  1.34 sys +  0.00 cusr  0.00 csys =  0.00 CPU)

Test if the database has a query cache
Time for select_query_cache (10000): 90 wallclock secs ( 5.81 usr  1.91 sys +  0.00 cusr  0.00 csys =  0.00 CPU)

Time for select_query_cache2 (10000): 91 wallclock secs ( 5.55 usr  1.86 sys +  0.00 cusr  0.00 csys =  0.00 CPU)

Testing big selects on the table

Testing count(distinct) on the table
Time for count_distinct_key_prefix (1000:1000): 39 wallclock secs ( 0.52 usr  0.17 sys +  0.00 cusr  0.00 csys =  0.00 CPU)
Time for count_distinct (1000:1000): 48 wallclock secs ( 0.56 usr  0.20 sys +  0.00 cusr  0.00 csys =  0.00 CPU)
