I performed a quick analysis on the performance of the site when navigating between various pages and it would appear that there are dozens of resources that are taking between 300 and 800 ms to retrieve from their source (DB or URL).

This is likely a direct symptom of the problems experienced yesterday and once all of those resources have been reloaded into the server cache the site will perform much better.

I would expect that we will see improved performance gradually over the next few days until everything is back to were it was before the crash. IMHO
