How to make load in JMeter on a large number of paths from a file?

Question

Software testing

I'm doing load through jmeter. You just need to make mass requests according to the list of urls in random order
. The profile has a CSV Data Set Config, from which the url for the ${SITE} parameter is taken. The ${SITE} parameter is inserted further into the HTTP Request. Everything.
The file contains about 17 thousand lines. I run load 30-60 minutes in 50 threads. If we analyze the Summary Report and check requests in IIS on the server during the test, we can conclude that requests are made only for 108 links from files.
I could not find information about the restrictions for CSV Data set config.
Is it possible to implement this profile differently, so that requests go through the entire list of links? Or maybe there are restrictions that can be reconfigured?

Answer 1

The problem was in the file itself. I decided to try to save it in txt. Everything worked.
