It's over 10 min so I kill the process. I think the reason is it's writing data line as a hash name and the data line can have 300.000 characters. I changed it so it only reads the index of the ID and then will just add 1 to it when I need the data. Then it's done in couple of seconds. Thanks for the tips with the index.
