It contains only 240 records... I have an another table without longblob
field with much much more records, and the query result is less than one second with
240 records with 11-15 sec... i think something wrong.
If i start a query, MySQL read 30-40 MB to memory! Why? I think, this
reading is the reason of the slow quare result.
