I had originally formatted this is for each date, 1 price per security. My dev’s asked me to change it to for each date, all securities one price. The difference in the first you get 500 dates with a price for each security before it repeats and does the same for the next security. A total of 300 securities. In the second one it is doing 1 date - then for 225 securities each gets a price before going to the next date. The first version completed in an hour - the second is taking 12 hours. Any thoughts? https://mockaroo.com/04eb4ad0----- As it turned out this was due to a misunderstanding of the term ‘rows’. This is resolved. I was trying to create 115,000 rows - which I thoughht to mean the combination of the nested node * the number of iterations in the main node. This was not the case. You do not count the nested iterations as a row.
