Tag History Calculation Query In A Report

Hello All,

Currently have a tag history calculation query as a report data source. It has 700ish tags within it and I am calculating about 5 values per tag. When going to preview the report ignition is throwing an error getting sample data and i briefly lose connection with the gateway. Is this number of tags unreasonable for a tag history calculation query? I would assume the tables are indexed properly to optimize queries since the tables and query are all IA out of the box. Any ideas are appreciated.
