Hi Forums,

I have a frustrating problem on my Stored Procedure. It can only proccess about 100 records in 10 minutes. I have 2 million initial records that need to processed. Meaning that with this speed i will around 200 days to finish all of them.
To make it worse, the data itself grows at least another 100 records per hour.

Really appreciated if anybody can help to speed this up.
