How to read many csv files in a loop

Hi everyone,
I need to read all the csv files contained in a library so that I can subsequently process the data thus obtained. I made a loop built like this: List files/folder > Table Row To Variable Loop Start > File Reader Loop End.
This loop is fine if there are few files in the library but it slows down a lot if there are many files: what can be done to increase the execution speed? Maybe there is a better way to achieve my goal?
Thanks in advance

Loops are slow by nature. If your files are identical and you can create one giant table from them in your use case you could read all files in the folder with one csv reader node and “Files in Folder” option
