Perform Load Testing for Multiple URL

I am new to Load Testing, I have a scenario in which we have multiple URL like below,

https://uat3.test.com/portal/test/test_launch.jsp?_p=bJ8yaD5BJ5DxZhTrayoOj3TnLMsobhY3EZAhTVO5pTXuPYS5gMosvKDeoAdoHVFgGyQYBgDQBIRgK9B0AuesfOg https://uat3.test.com/portal/test/test_launch.jsp?_p=qweqweqxczgfdx4rayoOj3TnLMsobhY3EZAhTVO5pTXuPYS5gMosvKDeoAdoHVFgGyQYBgDQBI123jsdfnsHHas https://uat3.test.com/portal/test/test_launch.jsp?_p=aerwesdvhfgasZhTrayoOj3TnLMsobhY3EZAhTVO5pTXuPYS5gMosvKDeoAdoHVFgGyQYBgasdasd3rfsgdhfds

Lets assume we have more similar URL like above and I want to launch all in a single go and measure the load/performance.

Please suggest which tool will be more flexiable to implement.(We are using Karate-Gatling currently)

Thanks,
