I found the problem: Normally, the same row could be found in Trackdata and EncodingData. The problem is, that we don't have a unique identifyer, so there are multiple items with the same StationID and ProdID. If I use a JOIN, MySQL seems to multiply the rows, therefore I know where the high load and the high processing time cames from :( I have to wait and see, if the guys decide to redesign the database, there are too much of flaws. Thanks for your help.
