Web page performance testing on web page which use javascript to load content

I want to do performance tests for the web page. I use the Gatling, but I've got this message: "This page uses JavaScript and requires a JavaScript enabled browser. Your browser is not JavaScript enabled." I've read Gatling documentation and I've found that Galting won't run javascript. There is the possibility to test this web page using Gatling? If not, how can I perform performance tests for this page? Which tools should I use?
