TTFB appears to take 4-5s for the Barack Obama article on the beta cluster and production for a 2G connection.
I'd like to understand where the server side work is happening to make this so high as this accounts for the majority of first paint time.
- [[ Analyse backend processing time | https://performance.wikimedia.org/xhgui/run/view?id=56ddcfdc7ed6ccf85595c206 ]] and work out what % of processing is contributing to the high time to first byte
- Suggest theories on why this might be happening and suggestions on how can improve this.
Output: report (preferably for beta cluster environment) listing where time in code is spent organised by function.
