Can you provide the table structure of the usr_tbl table along with the output of EXPLAIN?

Have you tried running OPTIMIZE and ANALYZE on the table before running the query?

Since you are doing a GROUP BY what is the size of your sort_buffer_size variable?

Great spirits have always found violent opposition from mediocre minds. The latter cannot understand it when a person does not thoughtlessly submit to hereditary prejudices but honestly and courageously uses their intelligence.
