Zendesk: https://gitlab.zendesk.com/agent/tickets/80555 Diff stats: - 22 files in diff - 44 additions and deletions. (2 lines changed per file) - Each file had ~8000 lines total The diff generation take anywhere from 45-60 seconds even though there are relatively few changes. We profiled the request and it appears that a lot of time is spent in highlighting. Are we highlighting the entirety of each file even though only a few lines are displayed?
