Subject:HELP --- Slow SP
View as plain text  
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.
