Vladan has provided a static FB newsfeed workload to measure TTI and DD times. Due to the size of the workload (includes some video clips), it's not attached to the bug. I've repackaged the workload here: https://people-mozilla.org/~sguo/fb-newsfeed-workload-feb27.tar.gz The nginx HTTP server needs to be installed to run the workload. The workload is captured from FB's production site, thus the involved set up required to run it. After unzipping, run the shell script mkcf.sh, which will create an nginx.conf configuration file. Follow the on-screen instructions from there.
