This is an MR improving performance of WebIDE. In all "After" measurements note Duration 0 for WebIDE: Project data measurement. This means that there was no time spent on the client to fetch the project data. The reason why it's not 0 when opening an MR is that the start mark for this measurement is fired right away, but the finish one will be triggered only after we request to open the very first changed file of the MR. Nevertheless, no project data request is sent when opening an MR.
