Hello!

Is the time spent generating data with the feed() function affecting the performance metrics reported by Gatling, like response times and throughput? I am logging into a file within my feeder so that I can crosscheck results in the end of the test and I am worried this might skew the results.

Hello,

Any blocking IO operation that’s not very fast is going to hurt performance and skew the results.
