Need to enhance (speed up) complicated MySQL select from many tables in database. If neccessary, suggest also table structure remake. Actually there are 12k rows in database and it will raise in future. The biggest problem is when making SUM from some cols, selecting time is about 15 seconds.
I will send you all tables structure and full select.
