so when same query query executed second time , it goes a lot faster like 1.5 --> 0,05 sec (in client program like forinstance HeidiiSQL)
2. I'm executing this many times via browser refresh so SQL is allways the same (also the same as at 1), but timing (sql_execution_time) is allways the 'same' 1.5s + a bit more.
Like caching would not work.
