Create a Thing (or 140) why is it so slow?

Hi,

im rather new to Bubble and not soo technical im afraid. So my very stupid question:

In my app I have something like a list of items/prices and I want to load this into my DB and say create 140 rows in DB for 140 items. Why does this take 1minute and not just 1sek or less? My source is the most basic/stupid CSV or XLS u can imagine. File size is “zero” almost and its super basic rows/entries…

What is the fastest way to do that? It there a limit, say bubble creates on 27 items/min? If so WHY?

thx
