What is that attempting to prove or replicate? Here's a simpler test I think replicates what I am indicating in GP comment, with regards to cookie handling: Not passing a cookie to the next stage; pure GET request: $ time curl -s -A "Mozilla/5.0 (X11; Linux x86_64; rv:102.0) Gecko/20100101 Firefox/102.0" -e ";auto" -L https://t.co/4fs609qwWt > nocookie.html real 0m4.916s user 0m0.016s sys 0m0.018s Using `-b` to pass the cookies _(same command as above, just adding `-b`)_ $ time curl -s -b -A "Mozilla/5.0 (X11; Linux x86_64; rv:102.0) Gecko/20100101 Firefox/102.0" -e ";auto" -L https://t.co/4fs609qwWt > withcookie.html real 0m1.995s user 0m0.083s sys 0m0.026s Look at the differences in the resulting files for 'with' and 'no' cookie. One redirect works in a timely manner. The other takes the ~4-5 seconds to redirect.
